I did a system upgrade a few days ago, that I had been delaying for a
few weeks. Probably nearly 300 packages got upgraded, including the
kernel, pipewire, etc. Since then, I keep having a recurrent problem
with audio distortion, which I haven't been able to pin down a cause for.
To start out, the audio is fine, using my ear bug headphones with my
laptop's audio jack. Then, after a few minutes, suddenly audio
distortion kicks in. It happens when using both streaming music
(audacious) as well as voice (zoom). I seem to be able to "clear it
out" by temporarily turning off my current audio profile in the
pavucontrol app, and then re-enabling it. But the distortion just
returns again after a few minutes. I've tried different headphones,
switching to laptop speakers, etc., but I still get the distortion.
I haven't been able to figure out which component or configuration
setting is causing it, and haven't seen any currently open bug reports
or any mentions in the Arch forums or here on the mailing list that
describe anything similar. Has anyone else been experiencing anything
like this and/or know what the cause or solution might be?
My laptop configuration is:
* linux 6.4.1.arch2-1
* pipewire 1:0.3.72-1 (with pipewire-alsa, pipewire-audio, and
pipewire-pulse also installed)
* wireplumber 0.4.14-1
* audio hardware: "Tiger Lake-LP Smart Sound Technology Audio
Controller Speaker + Headphones"
* selected audio profile: "Play HiFi quality music"
Thanks,
DR
