 I often have glitches while playing music or watching videos, I tried
 increasing fragments numbers, enabling high priority and high scheduling,
 and it still happens (seems to happen less often through). I tried to use
 verbose mode, it seems that each time I ear a glitch, there is the
 following message :
 I: module-alsa-sink.c: Underrun!
 N: module-alsa-sink.c: Increasing wakeup watermark to 71,27 ms

 another thing, if I let amarok pausing long enough, when I try to resume
 the playing, I ear no sound at all. If I try to quit amarok, it get hung
 until I kill pulseaudio
 I attach the output of pulseaudio when it happens. There's an error that
 seems to be reported :
 D: module-alsa-sink.c: Wakeup from ALSA! OUTPUT
 E: alsa-util.c: snd_pcm_avail_update() returned a value that is
 exceptionally large: 1157160 bytes (655 ms) Most likely this is an ALSA
 driver bug. Please report this issue to the PulseAudio developers.

 My soundcards are an M-Audio 2496 as input/output and a logitech webcam
 with built in mic as input only of course.
