Public bug reported:
Pulseaudio often crashes when using software like GTalk or Skype, simple
playback works fine though.
The interval between the crashes is random, from a couple of minutes to half an
hour usually.
My guess is that the problem is related to the fact that these applications
change the input volume while talking.
I've been able to reproduce the problem at will by performing a lot of "set
source volume" requests to pulseaudio using:
while true; do pactl set-source-volume 2 $((RANDOM % 80000)); done
the crash happens after few seconds.
Attached is the log of produced by running:
pulseaudio -k; sleep 0.5; pulseaudio -vvvvv 2>&1 | tee pulseaudio_output
The crash also occurs when running pulseaudio with "--no-cpu-limit" as
option.
I'm using Ubuntu 10.10 amd64 with all the updates installed, but I've
got this problem since 11.04.
