Is :testing for OLED currently up to date with kernel modules/configs from stock Steam OS in regards to audio system/handling?
I reinstalled stock Steam OS today on my OLED in order to see whether my issues with distorted audio are related strictly to Bazzite or it is a Valve's issue.
Well, it turns out audio is 100% fine on stock Steam OS.
Now I reinstalled back stock Bazzite (:testing branch rebase + setup with Bazzite portal) and my audio issues are once again back - occasional crackling and from very little to frequent audio stutters/distortions (imagine if somebody had 'playback speed' knob and would turn it down below 100% by a random value for a randomised fraction of second every ~second). Additional strange thing is that for most games it seems 'mostly' fine (although still happens if you listen carefully to the speakers) - however, it is very noticeable in rhythm games, when almost immediately you can notice that audio goes out of sync with prompts on the screen (due to those issues) - and the longer stage goes, the more out of sync it gets. This makes rhythm games unplayable on Bazzite whereas it's fine on stock SteamOS.
