I guess it stops at the point where pulseaudio crashes? Can you run pulseaudio in a terminal so that you see what the shell says when pulseaudio dies? Does it say "segmentation fault" or "killed"? If the shell says "killed", then pulseaudio probably consumes too much cpu time in realtime mode (there seem to be quite a lot of rewinding happening due to stream underruns and corking and uncorking, which might explain the excessive cpu use). This may be considered a pulseaudio bug, but I don't expect that anyone will have time to redesign the rewinding logic so that it would be more robust against clients that constantly have underruns and constantly cork and uncork themselves. If the shell says "segmentation fault", then we'd need a backtrace from gdb. > Is it PA bug or can i change some settings to fix it? If it's a cpu use issue, you can try working around it by setting "realtime-scheduling = no" in daemon.conf. -- Tanu
