ALC 4080 random static noise UPDATED!

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

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.

Long story short:

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.

ORIGINAL POST

----------------------------------------------------------------------------------------------------------------------------------

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?

Would be great to see any reward for people who digged this problem, wasted their time and effort instead enjoy their products and experienced all those "heart attacks " from random noise-blasts for all these months. Nice touch like a free games or something would be great. It won't cost anything for such large company to reward a few folks since you have all kind of promos all the time for ASUS products purchase anyway. Or pay and suffer is the only path with ASUS?

So, with the update, you haven't seen any issues so far. I'm so busy working that I had to pull back for a while.

I totally agree with you. I worked my buns off and lost many hours to make sure that sufficient proof was given to validate the problem.

You and Nuckels kept this thread alive. In my 20 plus years of working with a few board makers I have seen some like (VIA were I modded for a few years) reward users for their commitment to making good quality products.

Now, as for Asus, they aren't that bad (still get me upset because you need to draw, describe, repeat etc.) but I don't know if they do have that recognition for diehard customers.

Hi, z590 apex here. I was shocked the first time this static popped. It's a nightmare. The thing would just pop even when playing chess lol, it gave me the scare of my life.

I can confirm it can occur through the backpanel output jack and also the spdif output no difference at all even with the amplifier. I digged a bit on my side, did the firmware update, tried different drivers, I switched the gpu to another slot and the issue is still present and totally random. I've given up on it and disabled the hd audio in the bios and I'm now using a usb DAC.

I tried to contact Asus about it, they didn't seem to understand the issue and recommended that I rma the mb.

did you update to the latest firmware? in my case it seems that it has solved it.

I Updated firmware, still does it for me on Z690 Hero All driver versions.

I am using an Analog headset from Sennheiser on back speaker and mic in.

Interesting, I had actually along with many other issues in another thread commented on how I could not get the FW update tool to work, in Win10 or Win11, normal or admin mode or even in safe mode.

The tool would always just showed as blank with everything greyed out.
I got distracted by somebody in the house, went away for about 20+min and came back and now all the fields are populated and I can hit "start".

TLDR: if your FW update tool shows all fields as blank try leaving it running for a while and come back to it.

I still have this Issue with the Z590 Maximus XIII Hero Wifi.

My Sound Setup:

Rear Stereo output for Music and Internet Browser Sound.

Rear Line-In for my Audio Mixer.

Rear Microphone in for my dbx 286s.

Rear Digital Toslink for VoIP (primarily Discord)

Front Headphone for Game Sound.

When ever I play Games and listen to Music while being in a Discord VoIP Channel I will get blasted 100% of the time after some Minutes with static Noise.(Painfully loud)
When I am not in a VoIP Channel and listen to Music and play a Game most of the Time nothing will happen. But some Games still can trigger the static Noise while listening to Music.

Only the Front Headphone Port will produce the loud static Noise.

The newest firmware for the sound chip plus the newest driver finally, after 1.5 years, fixes the static noise issue for me.
However, now in place of the static noise, sometimes the whole sound stops playing and I have to reset the output by ending the playback. As in stopping the music, stopping the video, or restarting the game.
Realtek should just redo this chip. What a disgrace... Just like the media not reporting about it.
