Creative Sound Blaster Audigy FX Pro PCIe Sound Card review

[DukenukemX]

I'll just add that, with the onboards, like Realtek, I usually don't focus as much on which specific Realtek they use, but how it's implemented on the motherboard (which is what ends up being the sound). The Realtek itself only does basic amplification, so you still need an op-amp on the mobo if you want to drive headphones really well.

Sooo, if they take an ALC1220 or an 892, they still have to design the PCB around it, make sure it's getting nice clean power for both the digital and analog side, couple it with the right op-amp, and make sure the op-amp also has everything setup right.
That's both difficult and gets expensive really fast - quality capacitors, inductors, copper, all that passive stuff does affect the price of the mobo. Thus, you can mess up even the best-performing onboard codec just fine, or make a mid-line codec sound quite pleasant.

This happened to SoundStorm for Nvidia Nforce 2 chipsets as there were two DAC choices and nearly everyone went with the cheaper and of course massively worse one. SoundStorm was such a good sound chip that going after the digital output was well worth it. It's a reminder that motherboard manufacturers will always put the cheapest crap with good sound chips.

Last 10 years or so I've bought motherboards with the upgraded/isolated audio. Realtek offers a software based equalizer for their audio chips and I've been very happy with it. I love the "Powerful" setting. Makes a massive upgrade over the default install which has no equalizer settings applied.

Assuming you can get the equalizer. In some cases you need to get it from Microsoft app store. I've never gotten the equalizer from the app store. MSI has been pretty good at providing drivers that come with all the Realtek stuff.

I'm a Linux user. Linux audio is heavily influenced by core audio. Linux ALSA rivals core audio in quality and latnecy, though it has (sever) limitations which require the use of a sound server like pipewire for general use.

Pipewire is standard in most distros now. Not sure which distro uses PulseAudio?

Apple has the advantage of being 100% in control of their stack. All users have low latency low level audio access. Linux has been constantly improving sound systems. The pipewire server does a great job for every day things. Still end up needing ALSA/Jack to handle actual low latency stuff. It is superior to the current janky windows setup with ASIO... though inferior to the intergrated full low level stack that Apple provides with core audio. Can't wait to see how Microsoft screws things up with their new audio drivers. On the other hand if it does just work with hardware as Qcom/Yamaha are pushing for it might make windows ARM devices perhaps half way decent for pro audio. Might end up being a shame if they never push the improved driver to windows classic. (x86) lol [in all seriousness ARM hardware is perfect for audio production]

I've had a much better experience with sound cards in Linux than Windows. Just install Easy Effects and you get a very powerful equalizer. I also use QasMixer because whatever comes with KDE Plasma just isn't powerful enough to control my soundcard. It's a breath of fresh air knowing that I can find my audio settings quickly and not have to use Google to figure out how to find them in Windows 11.

 

[Mazzspeed]

Meh. I use whatever's built into my motherboard and it sounds great, even FLAC HD rips played back using Strawberry Music player sound amazing, and I'm pretty fussy when it comes to audio.

Dedicated sound cards are right up there with radio valves on headphone amps that usually turn out to be no more than valve looking devices with LED's to give them a valve like glow..

If I typed Pulse... I meant Pipewire. I mistype pulse often. It was pulse server for so long. ALSA is still the under lying HAL audio driver in the Kernel. Pipewire is the audio server that runs on top. Though it provides smooth desktop multi stream playback with zero hitching. Linux software can access ALSA directly (some audio players offer direct ALSA playback) ALSA can't support multi stream however meaning if you directly access ALSA other software can't. That is where pipewire comes in... acting as a server for all the audio requests. Jack (Jack Audio Connection Kit) is a alternate low level low latency server which to server audio and midi data. Jack and pipewire-jack are great but not the tightly integrated all in one that is Apples Core audio. Performacne is great but its just not as plug and go. They have made a lot of progress on Pipewire-jack. It almost makes it pointless to use jack2 anymore. About the only thing pipewire-jack is really missing is network audio. Which to be fair is probably used by a very very very small subset of Linux users. I mean most people using 10s of thousands in network audio gear are frankly.... using macs. I expect that the pipewire-jack project will continue to add features and mature. Jack will probably be abandoned eventually. Reminds me a bit of wayland / X. Pipewire has added 90% of jacks functionality but they aren't quite there yet.

Agree with you on windows. Thier audio system is so out of date. The idea that any audio card wouldn't just work with windows is so insane in 2026. But its MS.
To be fair they really do seem to have completely rebuilt a lot of problem systems with windows ARM. What they are cooking for the new ARM windows audio system sounds decent. More like Apples Core audio then what they are doing now. The issue of course will be trust, and hardware. I don't see a lot of audio professionals switching to Qualcomm windows devices. All MS new audio system does is catch it up to where Apple was a decade ago. I suspect that new system either won't be possible to port to windows classic x86... or MS will completely butcher it and break W!! sound playback. I am looking forward to the outrage posts this fall when a 11 audio update completely breaks windows audio for people running the lucky hardware that it won't like.

Just use Equalizer APO; completely sound card / vendor agnostic
Have been using it at work for more than a decade

see that's what i'm trying to avoid. most of the audigy line, being it was targeted at the home recording market, has a bit-perfect mode that bypasses the whole windows audio stack and sends the audio signal straight to the dac. if you've ever done any kind of audio work, mixing or mastering, it's a must have feature. between that and studio monitors you want to have your final product to sound good on all systems, not just your own. i mean the only thing i worked on was when i was still DJ'ing i would record dj mixes, but even if you were doing something like making youtube videos, if you had a system wide EQ running while you're working, you might have it sounding spectacular on your system, only to find when you play it in a car or listen at a friends house it sounded all kinds of f**ked up.

I should grab one...I'm still on a X-fi Fatality or whatever it was called....it works but I have to use a modified driver set that I don't think is maintained anymore just to use it on windows 10+

I could not get them to install and have always had to use the hacked one. that is the same card I have.

 

[Meeho]

Looks like an upgrade for my Asus Xonar sound card.

Is it, though? I've skimmed through the review but I didn't see anything worthwhile over my Xonar DX.

 

[III_Slyflyer_III]

I still rock a Sound Blaster AE-7, but I am still running a 5.1 Surround Sound setup, and I wanted to use the analog cable for 32-bit 96Khz sound vs. the Toss-link 24-bit 96Khz sound. Now, technically my old ears could not tell the difference on 24/32 front, but what I will say is, one, Toss-link added a noticeable delay if you watched characters lips in video games. Two, while Toss-Link does have very clean sound being digital to the DAC on my sound system, the DAC (for an internal card) sounds pretty damn good on the AE-7 with clean sound and with 0 latency added.
Ideally, HDMI to a Receiver setup would be ideal, but all this fits on my desk and on my floor for gaming nicely. I am still rocking the Z906 speakers for my gaming needs, probably the best 5.1 "PC Speakers" I have ever used, and simply stuck with them.

 

[DukenukemX]

It better be considering how old my Asus Xonar is.

 

[Mazzspeed]

I've still got my Soundblaster X-Fi, however being pci as opposed to pcie it's not much use anymore. I did run it under one of my Linux systems years ago before eventually ditching it for onboard audio as I honestly couldn't tell the difference.

 

[erek]

sad this card is just using an on-board audio chip anyhow, the Realtek ALC4082

 

[d3athf1sh]

there's still a few audigy RX's floating around for the same price (or maybe cheaper) and not a realtek chip in sight. you can even use it with the "daniel k" drivers and have all the same applications that used to come with audigy 2zs and audigy 4's back on win XP. studio grade cirrus audio adc/dac section. the last of it's kind and a bygone generation i suppose.

After going and really reading the full review. I have to really say this card makes almost zero sense. It is essentially a on board audio breakout board. Its not even good on board audio.

So this is an upgrade if your MOBO has absolute junk on board audio. It seems like its basically just your standard realtek... run through a old but okish digital->analog amp.

Honestly this reviewer was being very very kind to creative.
".... this chip contributes to a more controlled and consistent analog signal path compared to typical onboard implementations."
"... can translate into a cleaner and more consistent signal, particularly in systems where onboard audio is not optimally implemented."

Might as well just say, if your MOBO has decent onboard audio its identical to this card. OR perhaps better. After really reading this review my Gigabyte B450 pro wifi has a superior on board solution. It isn't audiophile grade either but its actually better then this. I paid like $150 or so for that board 5 years ago.

id have more respect for the card if it were a custom chip from creative at least

not an onboard audio breakout board

Indeed. Looking at this I would say 1/4 of the mobos on the market have superior on board audio. Of the remaining 3/4 I think most are very likely close to =. This is only an upgrade for boards with real crap after thought on board audio. So maybe if you bought a cheap dell or something. I imagine this isn't an upgrade in anyway for anyone that bought a DIY MOBO.

It also sounds like this card is actually internally using USB audio. So its basically a USB audio device in a PCIx slot. This has advantages for drivers... should be less likely that it in 5 years if Creative doesn't update drivers it stops working. On the other hand.... as I was saying earlier, why not just spend your $80 on a proper USB audio device. (or a little more on a better USB audio device if Sound really matters to you)

yep it’s got that asmedia usb chip,

“the ASMedia ASM3042 controller. This chip serves as a PCIe-to-USB bridge, effectively translating the PCI Express interface of the sound card into a USB-based audio pathway internally. That design choice is not accidental—modern audio codecs, including those from Realtek, increasingly operate over USB rather than the legacy HD Audio interface. The ASM3042 is a USB 3.x host controller, but in this implementation, it is used as a transport layer rather than for external connectivity.“

 

[DukenukemX]

Yea, this sound card is junk. Guess my Asus Xonar isn't going anywhere.

 

[d3athf1sh]

That design choice is not accidental—modern audio codecs, including those from Realtek, increasingly operate over USB rather than the legacy HD Audio interface.

the hdaudio header and whatever came before it is for your front panel audio ports on your case. nothing else. soundcards work without plugging that in.

No human can.

thats what the driver set was called I was talking about, been so long since I actually installed the driver.

 

[M76]

Tell me all about this latency. Please.

View attachment 794761

That's AI nonsense. 100ms delay is definitely noticeable, you might not catch 50ms immediately but you'd feel that something is off. If my USB DAC had 100ms latency I'd have thrown it out the second floor window.

 

[III_Slyflyer_III]

That shouldn't happen.

Actually, for 5.1 surround for gaming via Toss-Link, it absolutely should and does happen... the reason being the game sounds need to first be compressed and then encoded to DTS to fit within the max bandwidth. If I pumped out full Stereo through it, it would be uncompressed and likely no noticeable latency.

I do not use this method anymore, so it is a non-issue now, but it was present at the time I was using and testing it.

 

[d3athf1sh]

Now, technically my old ears could not tell the difference on 24/32 front

the benifits of 32bit float are really only realized on the recording end of things, because with 32bit float, no matter how loud you push it it's impossible for it to clip, so like if you recording a concert you wouldn't really have to worry about recording levels when things get loud, just set it and forget it. it does take a lot more disk space tho and at the same time you can still run 24 bit pretty hot without it clipping too, so..? and then again if you were mastering said 32bit recordings you would want to be able to hear exactly what you're working on before decimating/dithering down to 24 or 16 bit for distribution. but yeah like Meeho said you're not going to hear any difference playing 16 or 24 bit audio through it.

 

[sfsuphysics]

Oh man this brings back memories... every computer I'd build had to get a Sound Blaster card, early on it was because the computer speaker of beeps and boops was not sufficient, then later it just felt like something you HAD to do. Then one new build for whatever reason I didn't even bother with a sound card, and found that the onboard sound was really good enough for my tastes, and haven't bought any sort of sound card since then.

 

[w1retap]

I was kind of excited for a minute, seeing Sound Blaster, Audigy, Pro and PCIe all in the article. Then I zoomed in and there's a freaking Realkek on it. At least obscure it and put the logic inside a FPGA to make it look like you didn't just scrape the chip off an economy motherboard.

 

[WhoBeDaPlaya]

That's AI nonsense. 100ms delay is definitely noticeable, you might not catch 50ms immediately but you'd feel that something is off. If my USB DAC had 100ms latency I'd have thrown it out the second floor window.

Super easy experiment. Just remux an MKV with mkvtoolnix, while adding a +/- 100ms audio offset.
Immediately noticeable
On a related note, I do a lot of soft-subbing, and even a single frame of timing offset drives me up the wall

 

[Bankie]

Up until my last two builds I used sound cards in every gaming build. This time I went with a Creative DAC. More than enough. Nowadays you don't need to save CPU cycles anymore. Just need clean audio. A competent DAC is all you need. I'll never waste a precious slot on a sound card ever again. Especially if you build mATX like I do.

Yep, I'm still using an old SoundBlaster X3 DAC. It pushes my Fidelio X2HRs perfectly, has no detectable latency, and the X-Fi mode is probably the best software 3d audio feature that I've used (it's the one that has you take pictures of your ears and then builds a profile based on that and your headphone specs). Being able to switch between Headphones and Speakers with a button press is great. Also works in Linux with no drivers or configuration changes.

This Audigy card is probably an upgrade if you're on cheap onboard audio but I agree with others that it's probably a waste unless you want some specific feature that onboard doesn't have.

 

[Ranulfo]

This happened to SoundStorm for Nvidia Nforce 2 chipsets as there were two DAC choices and nearly everyone went with the cheaper and of course massively worse one.

Nforce1 (I think) on an Abit mobo is what convinced me to go usb mics and I have gone that way ever since. It did Dolby 5.1 ok with a cambridge soundwerks speaker setup but the mic port was horrible, completely unusable. I went back to a soundblaster card for my next build in '07 (stayed on XP) but went to mobo only with win7 a couple years later.

 

[ChadD]

That's AI nonsense. 100ms delay is definitely noticeable, you might not catch 50ms immediately but you'd feel that something is off. If my USB DAC had 100ms latency I'd have thrown it out the second floor window.

The AI is obviously giving the standard bs AI answer.
To perhaps give it a bit of credit. For audio playback that isn't actually wrong. If you have 50ms latency playing a video game or something you won't notice.
For recording audio, 100ms is for sure garbage. For recording you want sub 12ms. Or hardware that has a direct monitor mode.

Yup. It's like those (once) awesome Japanese audio brands that got bought out, and now their names adorn cheap Chinesium Temu crap.
I guess Creative has finally entered that phase

Oh well, I still have my Creative SB collection (CMS, 1.0, 1.5, 2.0, Pro, AWE32, AWE64 Gold, Live!, Audigy, Audigy 2 Plat) and all the X-Fis that are still being used (X-Fi Titanium, modded XtremeMusic / Gamer)

 

[Elf_Boy]

Just to set a baseline:

I don’t consider myself an audiophile — more of a tin‑eared gamer, honestly.

That said, there are a few things I pay attention to. Even though I find the Realtek onboard audio “good enough,” I rarely use it. I live in an apartment‑style condo and really don’t want to annoy the downstairs neighbors, so I’m almost always on wireless headphones (USB, not Bluetooth), using software processing only.

I’m also not independently wealthy, so my motherboards have always been mid‑range but solid — like my current ROG Strix X870E Gaming WiFi. I mention this because, like my previous two mid‑range ASUS boards (X570 and X670 chipsets), all three have only had two PCIe slots. One goes to the GPU, and in this build I have a card in the other. With PCIe slot scarcity, adding an internal sound card becomes much more difficult. Boards with more PCIe slots tend to involve resource sharing — using a slot often means losing an M.2, SATA port, or something else.

I also don’t fully trust Creative when it comes to long‑term software and driver support. Back in the day I was a big fan and always had a Creative Labs card in my system — right up until Windows 7 (or maybe Vista; it’s been a while). I had a fairly new card at the time, less than a year old, and after the OS upgrade it simply stopped working. No driver was available, and Creative chose never to release one. If it had been an older product, I might have understood, but this one was still current.

Anyway, I know plenty of people here have a much deeper and more visceral relationship with sound and music, and I don’t dismiss the value they find in hearing details I might completely miss. IDIC and all that. I’m coming from a different angle: I have hyperacusis, so for me it’s often about how low I can turn the amplitude and still hear everything clearly — because nearly every sound, from any source, feels like someone is speaking directly into my ear.

Oh, right — now that I think of it, I had a Turtle Beach sound card for a while too, and my first sound card ever was a Mockingboard C (Apple II). Setting IRQs and memory locations for DMA with DIP switches was more tedious than difficult — and I didn’t need glasses back then. I definitely don’t miss dealing with that level of hardware configuration anymore

Nice board and I like the look & features, lots of m.2's but only two PCIE:

“Conclusion​

The EQ offers safe presets, which allows a user to further tweak the lows, mids, and highs for a personal listening experience. Of course it all depends on the speakers you hook up to it. I found the Logitech Z906 offered a clean listening experience with the Audigy FX Pro. So who is the card suited for? If you have weak onboard audio such as the ES9260, which is 2 channel, then it makes sense to upgrade to a sound card such as the Sound Blaster Audigy FX Pro, and at around $79, it offers a great starting point for up to 7.1 channel audio.“

My how the mighty have fallen.

 

[erek]

"At first glance, the Sound Blaster Audigy FX Pro looks like a classic PCIe sound card, but that impression is somewhat misleading. The layout does not show a native PCIe audio solution in the traditional sense, but rather an architecture that operates internally via USB and is connected to the system through a PCIe-to-USB controller placed upstream. The card therefore does not use the PCIe x1 slot to address a true PCIe audio processor directly, but first to generate an internal USB path from it. That is perfectly legitimate technically, but it already explains why this card must be classified differently from older Audigy or X-Fi models with their own DSP foundation. Externally, Creative is selling a PCIe card here, but electrically speaking it is more of a well-implemented USB audio solution mounted on an expansion card carrier. This very discrepancy is what makes the PCB interesting."

"The digital signal path begins at the PCIe x1 edge connector. Directly behind the gold contacts are AC coupling capacitors, which remove the DC components in the PCIe link and pass the differential high-speed signal cleanly to the ASMedia controller. As usual, the reference clock comes from the mainboard, so the card does not need to build its own PCIe clock domain. The ASMedia ASM3042 accepts this PCIe connection and internally provides the USB path to which the Realtek ALC4082 is then attached. As a result, at its core the card is not treated by the operating system as a classic PCIe audio solution, but as a USB-accessible audio device with Creative software on top. That is the technical core of the entire product. From the ASM3042, a short USB 2.0 differential trace leads to the ALC4082. The actual audio codec is therefore not directly connected to the PCIe bus, but to a USB high-speed endpoint with 480 Mbit/s gross data rate. For audio streams, that is more than sufficient, even in multichannel operation and at high sample rates. The ASMedia controller is actually overdimensioned for this task, because it could handle far more than this card really uses. From a layout perspective, however, this solution has a practical advantage: the more sensitive audio codec can be connected internally via a short, defined USB path, while the more complex PCIe section ends at the bridge chip."

Creative Sound Blaster Audigy FX Pro Review – Teardown and Direct Measurement Compared to Onboard Sound in Idle and Gaming​

https://www.igorslab.de/en/creative...n-and-measurements-compared-to-onboard-sound/

"Final conclusion​

The Creative Sound Blaster Audigy FX Pro is not a bad sound card for just under 80 euros, but it is also not the return of the great dedicated PC audio magic. Technically, it is more of a cleanly designed internal USB audio solution on a PCIe carrier board. That is more modern, more pragmatic, and cheaper than a true dedicated audio processor, but also less distinctive. The ASMedia ASM3042 serves as the bridge, the Realtek ALC4082 performs the actual audio work, and the analog quality then depends on the power supply, layout, and output circuitry. That is exactly where this test is decided, not in the product name.

The PCB does show expertise. The power supply with local buck converters, downstream LDOs, ferrite beads, and separate decoupling is the card’s strongest technical aspect. Here Creative delivers more than mere minimum effort. The optical output is also a practical advantage, because it can provide the cleanest path out of the electrically noisy PC case, provided that conversion takes place externally afterward. Those who need TOSLINK get a plausible solution here. On the other hand, there is an analog implementation that is not sufficient against a very good modern motherboard. The MC4558C operational amplifiers used are solid standard components, but not high-end audio engineering. The headphone amplifier is usable for typical consumer loads, but not intended for serious high-impedance headphones. The lack of shielding for the analog section remains a disadvantage in a modern gaming system. More important, however, than any individual component criticism is the overall result: the card cannot turn its separate form factor into better analog output in a direct measurement comparison.

The measurement results are correspondingly sober. In idle, the MSI MEG X870E Ace leads with its onboard audio at the front connector and especially at the rear output. At the rear output, the motherboard achieves -93.2 dB(A) noise and 96.7 dB(A) dynamic range, while the Audigy FX Pro reaches -87.3 dB(A) and 84.6 dB(A). In pure THD, the Creative card is slightly better at 0.00285 % than the motherboard at 0.00318 %, but this advantage is too small and too isolated to offset the clear deficit in noise floor and dynamic range. Under gaming load, both solutions lose significantly, but here too the rear output of the motherboard remains more stable. The onboard audio then still reaches -70.3 dB(A) noise and 69.6 dB(A) dynamic range, while the Audigy FX Pro ends up at -67.1 dB(A) and 66.7 dB(A). The motherboard also remains ahead in THD+N, IMD+N, and IMD at 10 kHz.

This is perhaps the most important finding of this test: a dedicated sound card is not automatically better just because it has its own PCB. If a good motherboard already offers a strong audio section with a similar codec base, the add-in card must perform very cleanly in terms of layout, analog stage, and immunity to interference. That is only partially achieved by the Audigy FX Pro. It is more cleanly designed than a simple token card, but it is not consistent enough to beat a high-quality current motherboard in analog operation.

For owners of simple motherboards, missing optical outputs, or older analog multichannel speaker sets, the card can still make sense. It is a practical expansion, not a universal sound enhancement. It will often outperform weak onboard audio. Against a high-quality premium motherboard with well-implemented Realtek USB audio, however, it quickly becomes a sideways move and, in the worst case, even a small step backward. That sounds harsh, but it is more fair than nostalgic Sound Blaster glitter. In the end, it remains a technically interesting but conceptually ambivalent card. Creative is not selling a gimmick, because the card works, has genuine design advantages, and offers connections that are missing on many motherboards. But it also does not provide clear proof that a separate internal sound card is automatically superior in 2026. The Audigy FX Pro makes sense when you need its specific connections and functions. If, on the other hand, you only expect better analog measurements than from good onboard sound, you should look very closely beforehand. Or even better: measure. That was precisely the purpose of this little offense."

Actually, for 5.1 surround for gaming via Toss-Link, it absolutely should and does happen... the reason being the game sounds need to first be compressed and then encoded to DTS to fit within the max bandwidth. If I pumped out full Stereo through it, it would be uncompressed and likely no noticeable latency.

I do not use this method anymore, so it is a non-issue now, but it was present at the time I was using and testing it.

Not noticeable to me with it going to my Xbox from the TV to the control pod. Xbox is connected to the TV via HDMI, control pod to the TV via TOSLink.

I'm considering this but all I hear about creative software is pretty bad these days. I'll have to really check into that one.

I legit have been thinking that wearing my hd800s headphones are possibly going to make me deaf.

If I didn't need to talk to people while gaming with a mic I'd be using speakers.

Anyone have thoughts on headphones vs speaking with a sound card?

"At first glance, the Sound Blaster Audigy FX Pro looks like a classic PCIe sound card, but that impression is somewhat misleading. The layout does not show a native PCIe audio solution in the traditional sense, but rather an architecture that operates internally via USB and is connected to the system through a PCIe-to-USB controller placed upstream. The card therefore does not use the PCIe x1 slot to address a true PCIe audio processor directly, but first to generate an internal USB path from it. That is perfectly legitimate technically, but it already explains why this card must be classified differently from older Audigy or X-Fi models with their own DSP foundation. Externally, Creative is selling a PCIe card here, but electrically speaking it is more of a well-implemented USB audio solution mounted on an expansion card carrier. This very discrepancy is what makes the PCB interesting."

"The digital signal path begins at the PCIe x1 edge connector. Directly behind the gold contacts are AC coupling capacitors, which remove the DC components in the PCIe link and pass the differential high-speed signal cleanly to the ASMedia controller. As usual, the reference clock comes from the mainboard, so the card does not need to build its own PCIe clock domain. The ASMedia ASM3042 accepts this PCIe connection and internally provides the USB path to which the Realtek ALC4082 is then attached. As a result, at its core the card is not treated by the operating system as a classic PCIe audio solution, but as a USB-accessible audio device with Creative software on top. That is the technical core of the entire product. From the ASM3042, a short USB 2.0 differential trace leads to the ALC4082. The actual audio codec is therefore not directly connected to the PCIe bus, but to a USB high-speed endpoint with 480 Mbit/s gross data rate. For audio streams, that is more than sufficient, even in multichannel operation and at high sample rates. The ASMedia controller is actually overdimensioned for this task, because it could handle far more than this card really uses. From a layout perspective, however, this solution has a practical advantage: the more sensitive audio codec can be connected internally via a short, defined USB path, while the more complex PCIe section ends at the bridge chip."

"Final conclusion​

The Creative Sound Blaster Audigy FX Pro is not a bad sound card for just under 80 euros, but it is also not the return of the great dedicated PC audio magic. Technically, it is more of a cleanly designed internal USB audio solution on a PCIe carrier board. That is more modern, more pragmatic, and cheaper than a true dedicated audio processor, but also less distinctive. The ASMedia ASM3042 serves as the bridge, the Realtek ALC4082 performs the actual audio work, and the analog quality then depends on the power supply, layout, and output circuitry. That is exactly where this test is decided, not in the product name.

The PCB does show expertise. The power supply with local buck converters, downstream LDOs, ferrite beads, and separate decoupling is the card’s strongest technical aspect. Here Creative delivers more than mere minimum effort. The optical output is also a practical advantage, because it can provide the cleanest path out of the electrically noisy PC case, provided that conversion takes place externally afterward. Those who need TOSLINK get a plausible solution here. On the other hand, there is an analog implementation that is not sufficient against a very good modern motherboard. The MC4558C operational amplifiers used are solid standard components, but not high-end audio engineering. The headphone amplifier is usable for typical consumer loads, but not intended for serious high-impedance headphones. The lack of shielding for the analog section remains a disadvantage in a modern gaming system. More important, however, than any individual component criticism is the overall result: the card cannot turn its separate form factor into better analog output in a direct measurement comparison.

The measurement results are correspondingly sober. In idle, the MSI MEG X870E Ace leads with its onboard audio at the front connector and especially at the rear output.

Wow they really don't like it at a quick glance it says it uses Realtek in some way in the review.
