Package: pipewire
Version: 1.2.1-1
Seemingly randomly when a new audio stream is started, I get a completely
garbled audio output on this Dell Precision 5680 (card: Raptor Lake-P/U/H
cAVS). The issue is reproducible and occurs approximately after 1-2h of normal
usage. It survived a Debian reinstall and a fresh home directory, so it
shouldn't be caused by any non-standard configuration. It did not occur on
openSUSE Tumbleweed or NixOS which I had running for a few months without this
problem showing up.
I can reliably reproduce the issue within a few seconds by following these
steps:
1. Start a audio / video stream (to recognize when the corruption occurs)
2. Open pavucontrol
3. Move the output device volume slider up and down until pipewire hangs (takes
~5 to 10s on my system)
The volume notification sound of pavucontrol causes the pipewire daemon to
start hanging and the audio output to be completely garbled after a few seconds.
When the issue occurs the thread irq/206-AudioDSP and pipewire both max one CPU
core each. Pipewire does not react to SIGTERM, but a SIGKILL resolves the
problem for the next few hour or two.
