Digital audio distortion/corruption with Steam occasionally.

[horribleman]

I have a PC which I only really use to run games on Steam. The audio device is an RTX 4060ti, with spacial sound set to dolby for home theatre.

The audio is going via eRC through my LG CX into a Sonos Amp.

Occasionally (but frequently enough that I want to try to resolve it) the audio will start clicking and buzzing. It sounds as if the audio stream has been incorrectly sett to LPCM or something.

I don't have any audio encoding issues with other devices at all through the Sonos Amp, and it stops when I close Steam.

Does anyone know what settings I might need to change to stop this happening?

the tv is probably messing with the audio

grab a dp to hdmi adapter or cable (they are both directional)
then use hdmi audio directly to the receiver
set nvidia control panel to output only sound hdmi, and video to dp

You've ruled out any static electricity interference? And all the connections are fully secured?

Dust out case.

It's not static. It's garbled digital audio.

And the TV is not messing it up, I am using eArc with passthrough.

I think I figured out what it was. It's when the audio codec swtiches between games using dolby digital and the big picture mode sounds which I assume are encoded in stereo PCM or something.

Having windows set to 'spatial audio' to allow dolby digital be selected in sound options is not required to allow games to run in multi channel audio.

I think what was happening was the game was sending dolby 5.1 using its own encoders, and then when the game exited, windows tried to intercept and upsample the stereo to 5.1 and it gets messed up.

Disabling spatial audio in windows and setting surround sound for each game in the settings appears to have fixed this.

lets start with facts....no NgreedyA GPU supports real dolby digital live in game without modded drivers.....what modded driver set are you running to give the dolby live overlay???
