Public bug reported:
Audio is working fine on kernel 6.8.0-49 or lower. But after upgrading, I am
getting constant crackling or distortion in any audio source on my computer.
I have confirmed the issue by rolling back to a previous kernel version.
It's the same for any music/video file I play, and for streamed content
via a browser.
Audio is played through my monitor speakers over DisplayPort connection
from my AMD GPU.
