** Description changed:

  Binary package hint: pulseaudio
  
  I recently upgraded to Karmic from Jaunty with the update-manager. Since
  then sound output is somewhat broken. Normally everything is fine, but
  when an app is playing sound through pulseaudio and I change the volume
  with the pulseaudio volume control or the gnome-volume-control, the
  sound freezes. It continues to play the current tone, which sounds quite
  ugly. This happens not immediately, but only after the volume has
  changed a little bit. It goes away after more volume changes, returning
  to playing the sound just fine. Rarely, this problem occurs even without
  me changing the volume.
  
  I have an ATI card with an HDMI output, which is unused, and a Hercules
  Game Theater sound card with a Cirrus Logic CS 4614/22/24/30 chip.
  
  If I force an app to play the sound directly via ALSA (and not through
  the ALSA-Pulseaudio module, too!), then this does not occur.
  
  I added my user to the groups "pulse" and "pulse-access" (including
  logging out and in again), this did not change anything.
  
  I downgraded all pulseaudio packages to the version from Jaunty and it
  did not occur.
  
  Running the pulseaudio daemon in system mode does not help.
  
  If I run the pulseaudio daemon in a terminal with "-vv", I see the
  following messages on startup, which look suspicious to me:
  
  I: main.c: setrlimit(RLIMIT_NICE, (31, 31)) fehlgeschlagen: Operation not 
permitted
  I: main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) fehlgeschlagen: Operation not 
permitted
  I: core-util.c: Failed to acquire high-priority scheduling: No such file or 
directory
  I: core-util.c: Successfully enabled SCHED_RR scheduling for thread, with 
priority 4, which is lower than the requested 5.
  
  During playback messages like the following appear in the syslog
  sometimes:
  
  Nov  6 19:09:58 pc-philipp pulseaudio[3233]: ratelimit.c: 12 events
  suppressed
  
  Nov  6 19:10:01 pc-philipp pulseaudio[3233]: alsa-sink.c: ALSA woke us up to 
write new data to the device, but there was actually nothing to write!
  Nov  6 19:10:01 pc-philipp pulseaudio[3233]: alsa-sink.c: Most likely this is 
a bug in the ALSA driver 'snd_cs46xx'. Please report this issue to the ALSA 
developers.
  Nov  6 19:10:01 pc-philipp pulseaudio[3233]: alsa-sink.c: We were woken up 
with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another 
value < min_avail
  
  Attached is an output from pulseaudio -vv where I played a file through
  Rhythmbox and fiddled with the volume so that the problem occured.
