Created attachment 322736 [details] Log from running pulseaudio -v Description of problem: I opened a video from nautilus in totem, but the program just stopped. Nothing happened. I killed the program and opened the video again. This time the video played, but no sound. It seems that totem killed pulseaudio. I got this in messages: pulseaudio[29473]: module-alsa-sink.c: Error opening PCM device front:0: Enheten eller ressursen opptatt pulseaudio[29473]: sink-input.c: Assertion 'i->thread_info.rewrite_nbytes == 0' failed at pulsecore/sink-input.c:1150, function pa_sink_input_request_rewind(). Aborting. I started pulseaudio and tried the video again, but still no sound. Pavucontroll says it sends all audio to null output. I had started with verbose and found this: I: (alsa-lib)pcm_hw.c: open /dev/snd/pcmC0D0p failed I: alsa-util.c: Couldn't open PCM device front:0: Enheten eller ressursen opptatt I: (alsa-lib)pcm_hw.c: open /dev/snd/pcmC0D0p failed I: alsa-util.c: Couldn't open PCM device surround40:0: Enheten eller ressursen opptatt I: (alsa-lib)pcm_hw.c: open /dev/snd/pcmC0D0p failed I: alsa-util.c: Couldn't open PCM device surround41:0: Enheten eller ressursen opptatt I: (alsa-lib)pcm_hw.c: open /dev/snd/pcmC0D0p failed I: alsa-util.c: Couldn't open PCM device surround50:0: Enheten eller ressursen opptatt I: (alsa-lib)pcm_hw.c: open /dev/snd/pcmC0D0p failed I: alsa-util.c: Couldn't open PCM device surround51:0: Enheten eller ressursen opptatt I: (alsa-lib)confmisc.c: Unable to find definition 'cards.ICH4.pcm.surround71.0:CARD=0' I: (alsa-lib)conf.c: function snd_func_refer returned error: Ingen slik fil eller filkatalog I: (alsa-lib)conf.c: Evaluate error: Ingen slik fil eller filkatalog I: (alsa-lib)pcm.c: Unknown PCM surround71:0 I: alsa-util.c: Couldn't open PCM device surround71:0: Ingen slik fil eller filkatalog I: (alsa-lib)pcm_hw.c: open /dev/snd/pcmC0D0p failed E: alsa-util.c: Error opening PCM device hw:0: Enheten eller ressursen opptatt E: module.c: Failed to load module "module-alsa-sink" (argument: "device_id=0 sink_name=alsa_output.pci_8086_27de_sound_card_0_alsa_playback_0 tsched=1"): initialization failed.

This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Some other application is blocking access to the sound card, and hence PA cannot open it. This will cause PA to load the null output driver instead which unfortunately is not well tested and is documented in bug 475131. Finally, as PA mentions your audio driver is broken. The mixer information exposed to userspace by ALSA driver is bogus. That should be reported as seperate bug to the audio drivers. Closing as duplicate. *** This bug has been marked as a duplicate of bug 475131 ***
