https://bugs.launchpad.net/bugs/2092204 Title: Crackling audio in kernel 6.8.0-50 or newer Status in linux package in Ubuntu: Confirmed Bug description: 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.
