Pulseaudio crashes with audio video programs
by Sefyir from LinuxQuestions.org on (#50KZV)
Using Linux Mint 19.3
I've been using a/v chat software (linphone, jami, jitsi-meet, nextcloud-talk)
Repeatedly, "every now and then" ending or starting a call freezes PulseAudio completely. Audio and my camera break and firefox can't detect any devices at all. /dev/video0 stops existing as well.
Looking at PulseAudio Volume Control shows PulseAudio is having trouble connecting
Monitoring /var/log/syslog shows these logs (more at bottom) when it crashes
Code:ratelimit.c: 16 events suppressed
Mar 12 08:32:07 pulseaudio[3892]: [alsa-sink-HDMI 2] asyncq.c: q overrun, queuing locallyNone of these have any impact
Code:pulseaudio -k
kill PID (pulseaudio PID)
kill -s15 PID
kill -s9 PIDWhen I try to shutdown, Linux Mint warns me Sound and PulseAudio are not responding.
During the shutdown process, it completes the shutdown steps (using systemd) and just freezes. I have to hard power it off as I let it sit there for 20 minutes seeing if it would respond.
Once rebooted everything is fine like nothing happened.
I've never run into a unkillable process like this in Linux!
Not sure what to do
