Audio issues with AMD F13 on Fedora 41

Framework Laptop 13 Linux
1

I’ve recently been having issues with audio playback on my F13 laptop. No matter what source (Spotify, Chromium, Firefox, Rythmbox) or audio device (internal speakers, HDMI, wired, and bluetooth headphones) I use, the audio stutters every few seconds. This became noticeable a few months ago – it might have occurred when I upgraded from Fedora 40 to 41, but I can’t be sure.

I am using coppwr to monitor Pipewire. This screenshot was taken when playing a .m4a file from Rythmbox:

I have tried deactivating powersave for the sound card as mentioned in the Arch wiki, with no change. The audio stuttering occurs no matter the state of PPD.

I have also tried a fresh install of Fedora 41, and once again there has been no change. This suggests this could be a hardware problem (maybe memory?), but I do not know enough about linux audio to confirm this.

Any help would be welcome!

Try adding amdgpu.dcdebugmask=0x10 to your kernel boot options. Solved it for me, so seems related to the video stutter that other people are having.

I noticed it’s worst when the GPU is not very active.

I have applied the kernel options and have now been listening to webradio for more than 10 minutes suspiciously. But indeed - no stuttering since now. You seem to have solved the problem. Thank you! :blush: :pray:

I’m confused.

If my research is correct, all setting amdgpu.dcdebugmask=0x10 does is enable DC Core level logging. Can anyone explain why enabling DC Core-level debug logging resolves these sound issues?

It disables Panel Self Refresh.

Some people are noticing frame time stutter as well if they don’t set this flag. I had those too I think, but not very clearly. The audio problems were very noticeable though.

With kernel 6_12_12 it’s fixed

So I can remove the kernel option amdgpu.dcdebugmask=0x10?

I had no audio cracklings after removing it for quite some time. At least 6 hours of spotify playing
