I've tried multiple "solutions", but nothing worked so far. I'd really like if audio worked normally, as this is making me hard to do video meetings on my Ubuntu rig, which I use for development. When the issue occurred first, I was using STOCK settings. Only thing that I've added to pulse conf was an auto-select for the correct devices: ``` set-default-sink 0 set-default-source 2 ``` I did try the following to no avail: `load-module module-udev-detect tsched=0` `load-module module-echo-cancel source_name=noechosource sink_name=noechosink` `pulseaudio -k` seems to fix the sound for a few minutes. As I've read, many Ryzen owners have similar issues. I'm more than willing to try out different package versions, settings - you name it.
