[ubuntu-uk] Keep losing sound

[David King]

Well, I lost the sound again. I tried closing various programs that were 
open, Firefox, Flock, Sunbird, Azureus, Thunderbird, but none of them 
made any difference. I even closed pulseaudio via the System Monitor.

When trying to restart pulseaudio I get the following:

$ pulseaudio
W: pid.c: Stale PID file, overwriting.
E: alsa-util.c: Error opening PCM device hw:0: Device or resource busy
E: module.c: Failed to load  module "module-alsa-sink" (argument: 
"device_id=0 
sink_name=alsa_output.pci_1002_4383_sound_card_0_alsa_playback_0"): 
initialization failed.
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL front:0


This seems to suggest that the soundcard is busy, even though there is 
currently no sound from it, nor anything that I can determine to be 
playing any audio.
