Binary package hint: pulseaudio

During playback of audio, I frequently (3-4 times a night) encounter the
problem that during playback audio suddenly is skipped. It then sounds
like when you fast-forward a CD in a CD player - a small fragment of
audio is played correctly, after which a new fragment from further down
the track is played etc.  The audio track is also finished too early.
When this occurs, I get the message I: module-alsa-sink.c: underrun.
Killing and restarting pulseaudio fixes the problem, until it happens
again.
