** 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.
