Realtek ALC4080 Audio Problems. Sound Cuts out with Loud Hiss.

[bencrutz]

Hello, I'm new to this forum but you all seem very knowledgeable and I'm stumped here. Maybe someone here can think of a new fix to try.

My trouble is with the sound (Realtek ALC4080) on a new motherboard (MSI z590 Torpedo) motherboard on a (mostly) new PC build.

Using the TOSLINK audio output, the sound will work normally for some time but suddenly and randomly the sound will cut out and a very loud hissing sound is output instead. It happens randomly and sporadically. Some days it won't happen at all, other days it happens several times every hour.

Any thoughts on what I can I do to make this audio output behave normally? Do you think it's a hardware problem or a driver issue?

Some notes from testing and research:
- Issue does not occur with any other audio outputs. TOSlink only.
- Tested, confirmed that the cable is not the cause.
- Tested, confirmed that the receiver is not the cause.
- Found several threads about this issue with the alc4080 on motherboards from a variety of manufacturers but I haven't found word of a fix.
- (It seems incredibly common for forum-posters to suggest "just buy a sound" card but that's a distraction from the issue at hand.)

Here's what I've tried so far:
- Windows, Windows Update, BIOS, and Drivers are all latest versions. Drivers via manufacturer.
- Tried resetting the CMOS but it didn't help
- MSI support suggested to disable Intel C State in the BIOS, but it didn't help. (Their other emails are poorly written to the point of futility.)
- Realtek support did not respond to my question.

you might wanna upgrade the realtek fw

‎Hello! I have a similar problem on the board ROG MAXIMUS XIII APEX.Wrote in support of asus waiting for an answer I think the problem is in the firmware of the audio codec ALC4080.I shot a video on my phone and poured on youtube here is a link

and I also found a video of a user of the same motherboard as me and he has a similar problem (

) he says that those support asus said that this is supposedly a marriage and you need to hand over the fee, but SPDIF they somehow patched so that it does not hiss. I don't know what to do hopefully the problem is in the firmware!‎

Привет ! У меня подобная проблема на плате ROG MAXIMUS XIII APEX .Написал в поддержку asus жду ответа думаю проблема в прошивки звукового кодека ALC4080.Я снял видео на телефон и залил на youtube вот ссылка

и еще я нашел видео пользователя такой же материнской платы как у меня и у него аналогичная проблема (

) он говорит что тех поддержка asus сказала что это якобы брак и надо плату сдавать , но SPDIF они как-то пропатчили, чтобы он не шипел. Не знаю что делать надеюсь что проблема в прошивке !

You can find a link to mentioned MSI motherboards, where the Realtec bug is fixed with the lastest audio driver update 6.3.9600.2286.

I would just use a discreet Sound card at this rate.

Hello, I have the same issues, but instead of TOSlink, i use the 3.5mm output on the motherboard. I think i might've found the culprit. I think its a driver issue. I found that, if you start windows on fresh start (disable fast startup in control panel, under 'Power Options') the issues seems to gone away. I haven't had any loud hissing for months now. But, when i put the computer to sleep, after turning it back on again, i found that the issue is back. Literally makes me jump out of my chair when it happened.

It could be that the driver seems to be faulty if it were not freshly start upon sleep or shutdown. I don't know anything about driver stuff, but i guess the workaround to this is to fix the driver.

Motherboard model:
- Gigabyte Z590 Vision D

im having the same issue the russian guys video describes it exactly im using the analog audio outs
i hate that these alc4080's do not like exit a suspend state essentially u can play audio in one tab of chrome pause the video wait a short amount of time play the video or go to another youtube tab and BAM very loud distortion its as if the firmware is either not telling the os to wait for sync or the windows is not waiting for it
USB audio ICs(specifically the alc4080) should never be used in motherboard audio ever again makes trying to save a buck and get a decent z590 OC board a bad buy

gigabyte z590 aorus ultra and yes i got the intel i225v 2.5gb lan with the suddenly say "cannot start" and or not properly power cycling forcing me to fully shutdown and unplug my psu to get it running again

gave up and got a sound blaster z

try updating the firmware for your Z590 vision d board - direct link to it here. (firmware update released around mid-july 2022)

yea kinda sucks that Gigabyte tried to follow MSI in putting ALC4080 chips onto some of the gigabyte z590 boards (most MSI z590 "gaming" boards have either alc4080 or alc4082); Gigabyte only provided updated firmware but no updated usb audio drivers since v6.3.9600.2306 but a 6.3.9600.2330 realtek usb audio gigabyte version is available from the station drivers site since late November 2022; don't know why Gigabyte themselves don't provide this updated driver version on their web site. maybe trade in that Z590 aorus ultra board with either Z590 Aorus Elite, Z590 Aorus Master or Z590 Aorus Extreme boards, which these specific z590 boards use Realtek ALC1220-VB instead

I found the Realtek ALC4080 version for an USB Audio version for a high quality audio system a complete disaster, and should have been abounded by MSI .
I now have complete disabled all Realtek option in the BIOS as well as drivers, which actually was a huge problem, because the Realtek ASIO still remained.
I now use Topping D10 for driving the local PC fairly decent speakers, and the DX1 for headphones and the external high-end audio system.
Just for the local PC system the audio quality far exceed the motherboard audio system many times!
I have now learned, that integrated audio system is of no go, if high quality is required, and this has a significant extra cost.
