Аудио контроллер realtek alc4080

The “new” ALC4080 is also better than the usual onboard call, but also has some significant disadvantages. The codec itself is absolutely fine and a blind test with sensitive low impedance headphones will reveal a slight noise floor at most, but this also depends strongly on the external circuitry and the selected gain. Otherwise it is a differently connected solution very similar to the ALC1220. No more, but also no less.

You have an ASUS ROG SS3|DTS Sound Unbound motherboard with ALC408x codec, so :

You need Realtek USB Audio Drivers (UAD — ASUS ROG SS3-DTS MB) from the first post of this thread : [DRIVERS] Realtek USB Audio (MB | Intel 5xx & AMD 5xx/TRX40).

Follow scrupulously your CLEANUP process then your INSTALL process, for the next drivers packages that I would release, you will can directly follow your UPDATE process.

Once it’s done, follow these 2 TIPS :

1) Disable hibernation :

— Don’t touch to the default sampling rate (48000Hz 24Bits) in a first time to test (for information, DTS Sound Unbound is incompatible with a sampling rate above 48000Hz 24Bits).
— If you want troubleshoot drivers side (in order to provide ASUS Support with more targeted elements of the possible root cause), take a look at this post.
— If that doesn’t fix or reduce your issue, open a ticket with ASUS Support (and/or you can post in ROG Care section : ROG Care).

First of all I want to notice this issue is not present on ALC 4082 analog outputs. So, no sense to tweak anything in OS since ALC 4080 codec gives static sound out of the box. Firmware fixes only ALC 4080/4082 SPDIF static noise but not analog for ALC 4080.
Sampling rate change or default settings won’t eliminate random static noise. Same behavior occurs if Realtek audio drivers (incl. SS3, SR and DTS) are NOT installed at all, just Windows audio driver on clean WIndows 10 installed OS.
ASUS support insist this is a faulty motherboard which should be RMA and completely ignores the fact that many Z590 boards with ALC 4080 codec have this issue, even from other vendors. This is not just particular motherboard or model problem.
RMA in this case will be problematic because problem can occurs randomly and in circumstances when person should rewind videos or audio tracks. Which will take a while and I have a doubts someone will rewind all this stuff all day long for several days just to catch it. More likely they will test motherboard for few days and say that board works fine. This is not the case when you launch stress test and check results later. + I saw reports from users who had the same issue with replaced Z590 after RMA. Replace «faulty» Z590 motherboard with another «faulty» Z590 motherboard with ALC 4080 or pay even more extra for ALC 4082 board? I’d say even more, if this is a board malfunction, why this static noise over analog outputs is just not play always? Why only in some circumstances? It have the same behaviour SPDIF output had before firmware upgrade.
If this is a hardware design flaw, they should admit that and do a recall or they\Realtek should revisit ALC 4080 firmware\ boards BIOS and check if they can fix analog outputs behaviour or not. Because end-user just cannot do anything at his end.

I’m not even touching long WIndows boot issue https://www.tenforums.com/sound-audi. 90-issues.html
Or usb devices hangs during boot with Realtek audio drivers installed on ALC 4080 boards if you have few external HDDs or pendrives plugged in rear usb ports.
They (vendors) just ignore this almost for 6 months. They will play dead till the end, while they can and do not admit anything if they cannot fix this. Known strategy.

ALC 4080 random static noise (M13Apex)

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

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.

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.

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):

Fresh Windows 10 install (latest updates).
i7 11700K
ASUS ROG MAXIMUS XIII APEX
G.SKILL F4-4000C19D-16GTZKW
Gigabyte GTX 1660 Super Gaming OC
EVGA SuperNOVA 1000 P2

Asus XIII boards are in general crap, especially Apex XIII, which is FUBAR.
I feel you man, couldn’t return mine either, 500 Euros thrown down to the toilet. I decided just to give up, does not worth time, energy and being continuously annoyed trying to make work something which is by default a bad design, having bios written Friday afternoons remotely and so on.
*Very nice job, Asus!*

Had the same in ROG STRIX Z-590A Gaming. When installed latest drivers from this forum (thanks MoKiChU) it stopped or it rarely happens.

I have suspicions that changing sampling rate for analog outputs to anything different than stock settings can be cause of this issue but I’m not sure. I’m still testing. By default sampling rate settings in my case are 48000Hz and 32Bit.
Can you check please your current sampling rate in Windows sound settings? And if they are same as mine could you change it to something like 48000Hz/24Bit or 192000Hz/32Bit for couple of days, just to check if problem appears again? Thanks.

Am having the same issue with my ROG Strix Z590-F. Randomly sound will just go to a static hiss, mainly during video but has happened once in a game too.

Going to sound settings, changing output to another option and then back to Realtek USB Audio resolves it — until next time.

(Latest drivers from ASUS installed and the firmware update)

Just for clarification, are you speaking of analog audio outputs? Could you post your current sampling rate from Windows settings and also, if you know, is your RAM running in Gear 1 or Gear 2 mode?

All settings are the default — 24bit 48,000Hz sampling rate
Realtek USB Audio is the analog output for speakers.
As for my RAM I’m not sure of that setting but again I haven’t changed anything so I suspect whatever the default is!

Just had a short conversation with a guy who have the same problem on his M13Apex too with 5.1 analog outputs. He also claims that the issue occurs more frequent with 192000Hz\32Bit sampling rate.
His video:

i have the same static noise issue with two ROG Z590 F Gaming WIFI Mainboards.
All i know so far, it has nothing to do with overclock, drivers, Bios or sound settings, it is complete random.

Windows loudness control is stuttering and System Sounds are delayed all the time.
It is most likely a Hardware design issue.

340 Euros for the toilet. good Job Asus
