[Bug 212493] Re: mplayer pulseaudio freeze

[Stefano Rivera]

I see the same behaviour in current jaunty. Video seems to be jerky for
a fraction of a second directly after resuming / seeking, then it
settles into steady playback. This has the side-affect of making
repetitive seeking irritatingly slow. Playback seems generally unsteady.
Killing pulseaudio and using alsa stops this misbehaviour.

The best way to recreate it seems to be to pause a video, adjust the
volume using the volume keys / mixer, and toggle play/pause until it
hangs.

>From the following debugging, it looks like the issue is in
communication with the pulseaudio unix socket:
