Title:
Random noises with 5.13.0-37-generic but not with 5.13.0-35-generic
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
After a recent update to linux-image-5.13.0-37-generic, I started
experiencing random noises about every five seconds. After rebooting
into linux-image-5.13.0-35-generic, the noises were gone.
Some details that I've noticed:
1. When launching pulseaudio manually, not as a daemon, the problem
disappears.
2. If I set the log-level in /etc/pulse/daemon.conf to debug and
reload it, the log has a lot of:
Mar 23 17:22:44 ainar-ThinkPad-X13-Gen-1 pulseaudio[76435]: Wakeup from ALSA!
Mar 23 17:22:43 ainar-ThinkPad-X13-Gen-1 pulseaudio[76435]: Wakeup from ALSA!
Mar 23 17:22:39 ainar-ThinkPad-X13-Gen-1 pulseaudio[76435]: Wakeup from ALSA!
Mar 23 17:22:38 ainar-ThinkPad-X13-Gen-1 pulseaudio[76435]: Wakeup from ALSA!
Which roughly correspond with the noises.
3. The usual "rm -f -r ~/.config/pulse && pulseaudio -k && sudo alsa
force-reload" doesn't seem to help. Only a kernel downgrade does.
4. This happens both in Firefox (where I first noticed it) as well as
in Totem and in system sounds.
5. I tried to report the bug using "ubuntu-bug audio", but it showed
me six inputs of which three looked the same, and for each of them it
told me that it pulseaudio wasn't configured to use it. I'm ready to
collect logs and other info within the next days.
