Sound Gets Garbled After Launching Pavucontrol

My laptop has an Intel soundcard and the audio is managed by sof-firmware and pipewire. The sound works fine as long as I do not launch pavucontrol (modifications through the tray icon work okay as well). However, when I launch pavucontrol to change any setting, the sound gets very garbled. The problem does not go away unless I reopen and reclose pavucontrol multiple times: the sound sometimes gets even more garbled or garbled in a different way during these runs, and sometimes just one rerun is sufficient. Restarting pipewire also solves the issue.

I am also using TLP for power management (which sets /sys/module/snd_hda_intel/parameters/power_save as 1), and I tried disabling it, but the behaviour persisted.

Any ideas about the cause?

I have the same problem, on a Thinkpad X1 Yoga Gen 5! Restarting Pipewire always solves the problem for a while, but requires restarting the browser for example.

This has been a problem for the past few weeks. With every update, I'm hopeful that the problem will be fixed, but that hasn't happened so far!

My machine is also a ThinkPad! It is still good news to hear that this is a recent problem though; my install on this PC is fresh and I thought this was a permanent issue.

Re: Sound Gets Garbled After Launching Pavucontrol

Hi, maybe same issue for me. Random "robotic" sound from speakers and headphones (Intel Alder Lake soundcard)

This issue described here:

https://gitlab.freedesktop.org/pipewire … ssues/3353

Check comments "Kernel regression in kernel versions higher than 6.4"

LTS kernel probably solve this issue for now.
