Dear PulseAudio hackers,
I try to hunt down a situation where PulseAudio uses over 100 % of CPU
load. I can reproduce it by running `gnome-volume-control` which starts
`gnome-volume-control.pulse` I think.
I followed HowToDebugCPULoadBugs and HowToUseOProfile and this is what I
got.
{{{
$ sudo opcontrol --start
Using default event: CPU_CLK_UNHALTED:100000:0:1:1
Using 2.6+ OProfile kernel interface.
Using log file /var/lib/oprofile/samples/oprofiled.log
Daemon started.
Profiler running.
$ # start and quit `gnome-volume-control`
$ sudo opcontrol --stop
Stopping profiling.
$ opreport -l /usr/bin/pulseaudio

I am using Debian Sid/unstable with the following versions.
{{{
$ LANG=C dpkg -l pulseaudio gnome-media

}}}
Please tell me what else you need. I looked through the changelog of the
version in Git but did not notice any important changes (only compile
fixes and so on) so refrained from installing Git HEAD on my system.
Thanks,
Paul
