UPDATE 3: Ok. So I've repro static noise using ASUS Dual Intelligent Processors 5 like Sasha did in his video. If you can't repro, try to use different songs, higher volume level and higher samping rate e.g. 192000 Hz and 24 Bit. Audio track in my video: Metallica - Sad But True. Volume level: 20%. Speakers: EDIFIER R2750DB (line 1 RCA) and rear Realtek audio out (lime). Also there is same weird sound cuts when I switching AI Cooling toggle and my mouse hangs sometimes for a second and not reacting (tried with SteelSeries Sensei Ten and ASUS ROG STRIX Evolve). When static sound plays you can see how volume slider is being slightly unresponsive, it's lagging when I change volume. No errors, same behaviour with BIOS optimized default settings, different BIOS versions and even on clean Win 10 installation without Realtek driver (with Microsoft default audio driver). This sound issue can occurs everywhere. Dual Intelligent Processors 5 - it's just the fastest way to repro this issue. Imagine what people feel when this crap happens suddenly at the high volume when people don't expecting this at all Video:
UPDATE 2:
Today I caught this hiss in the BIOS. I don't know how to reproduce it in Windows but I know how to trigger this static sound via analog outputs in the BIOS. Here's how to reproduce it:
1. Change your CPU vcore voltage in the BIOS to any value which will get you BSOD under stress. Unstable overclock or unstable undervolt, doesn't matter. 2. Set this voltage and launch something like Cinebench R23 or any stress load to get BSOD. 3. When you will see BSOD screen - use reset button on your chassis or motherboard (don't wait while Windows will reset PC, reset it manually). 4. Enter the BIOS and static sound will be there. It will be more quiet than regular sudden static noise in Windows but you can hear it via analog outputs and it will have the same character, until you exit the BIOS and start Windows boot.
P.S. if this won't work for you, try to reproduce it again with chassis front panel audio output.
One more method how to catch it under Windows (might take some time) from another 13 Apex owner using Dual Intelligent Processors 5 app (there is also weird sound cuts when he switching AI Cooling toggle, I suspect this is not normal too). 5.1 speakers, 192000Hz 32Bit, analog.

UPDATE:
Igor's Lab digging this problem with analog static noise and cuts out.
Now we come to the actual problem, namely the dropouts, sporadic volume changes and even a (rather rare) unmotivated "pop" when the volume control is set above 50%. Here I have used my manufacturer contacts and asked directly to the producers and their development departments. If you believe the first findings of the FAE (Field Application Engineer) involved everywhere, the problem even lies outside the audio chip, namely in the MCU (Micro Controller Unit), which is responsible for the RGB effects of the individual components.
Asus Maximus XIII Apex onboard ALC 4080 audio codec makes static noise over front or rear analog audio outputs. Happens absolutely random and unpredictable. When I rewind videos on YouTube or rewind\change audio tracks in music player but never in games. Usually once a day. Asus support insist this is a faulty motherboard and recommend to RMA board to local seller but I saw few messages from Rog Strix Z590-F and Z590-E owners who have exactly the same issue (since these boards have ALC 4080 codec too). Some owners encounter exactly the same analog outputs issue with other vendors ALC4080 motherboards (Gigabyte\Aorus\MSI). Realtek audio drivers uninstall does nothing, static noise randomly repeats. SPDIF firmware for ALC 4080\4082 is applied. I never had this issue over SPDIF by the way. Any ideas what else to try?
Static noise example (if video doesn't work here, open it on YouTube):

I don't see your question in this post before now,
Either I'm confused or your question doesn't make sense. the majority of people use that output to drive their speakers because it's the codec on the board. We aren't talking about amps and digital adapters, just plain sound codec. You have the same codec. Why don't you say what you're getting at or maybe the nature of your question so at least I can understand.
This is Windows 11 but my Win 10 shows the same thing. USB audio goes through USB ports.. Normal audio is used for the analog outputs on the back.. The USB audio in the second attachment is for my VR headset with uses USB audio..

ALC4080 and ALC4082 are designed that way. They using USB via chipset lanes. if you can't see USB, that's only means that you installed not full pack of drivers or driver is not fully compatible Windows 11. Doesn't matter. What is matter - in fact it's still using USB, Like you or not. Fact.

Can you stop offtop in this thread? We are trying to solve serious problem. I don't care where that driver was taken from. It's unofficial and I don't care how it works and what it shows. Our issue is hardware related anyway.
Saltgrass wrote: @AguchoB.. You can say it all you want but it doesn't make it true. But the bottom line I am not having a problem with the 4082. If nothing else, try using the other version to see if it makes a difference.
It won't cancel the fact that 4082 use USB via chipset lanes. This is how both ALC4080\4082 work. ALC 4082 don't have this issue and this is pointing that is ALC4080 hardware design flaw or amplification issues. Please stop your pointless offtop.
