Xbox Media Center seems to have a share of problems on my system. The most recent events has been that the audio seems to crash, either going silent or getting stuck in a endless loop that’s quite annoying. This seems to happen quite often if I jump in movies.
The first solution, rebooting the system, wasn’t exactly neat. The second is sort-of work-in-progress. But it seems to work which is nice:
Then either before I start XBMC or when the problem occurs I run:
sudo killall pulseaudio
ps aux | grep pulse
If there still is pulseaudio processes left I kill them with
sudo kill -9 whateverprocess
I think this happens mostly when I has been running XBMC and the audio is hung. Of course the ideal thing here would be to disable pulseaudio completely, or to pray for team-xbmc to fix this. I have not decided what to do yet, I have to do some reading on this PulseAudio, it might be there for some other reason than to break XBMC.
