Not sure what happened, and I don't know where to look for processes that are
maybe orphaned, or running wild..
I tried to play an MP3 with mplayer now it says:
Could not open/initialize audio device -> no sound.

I have this process running:
/usr/lib/gnome-volume-manager/gnome-volume-manager --sm-disable
/usr/bin/timidity -Os -iAD


a video in Firefox doesn't say anything, it is just silent.

Amarok opens and says:
xine was unable to initialize any audio drivers.

I forget what app I tried, but I do recall one saying that the device was
being used by another process, but I can't find anything running. where to
look?

looks like this did it:
# /etc/init.d/alsasound restart
Shutting down sound driver: ERROR: Module snd_hda_intel is in use
ERROR: Module snd_pcm is in use by snd_hda_intel
ERROR: Module snd_timer is in use by snd_pcm
ERROR: Module snd is in use by snd_hda_intel,snd_pcm,snd_timer
done
ALSA driver is already running.


because now MP3's play again in Amarok. not sure what stopped it, why it
was "in use", or what happened!

tried to stop & start some sound processes:

# /etc/init.d/timidity restart
Stopping TiMidity++ ALSA midi emulation....
Starting TiMidity++ ALSA midi emulation...ALSA lib pcm_dmix.c:996:
(snd_pcm_dmix_open) unable to open slave
failed!

# /etc/init.d/alsasound restart
Shutting down sound driver: ERROR: Module snd_hda_intel is in use
ERROR: Module snd_pcm is in use by snd_hda_intel
ERROR: Module snd_timer is in use by snd_pcm
ERROR: Module snd is in use by snd_hda_intel,snd_pcm,snd_timer
done
ALSA driver is already running.


so Module snd_hda_intel is in use, how do I restart/kill/re-enable it??
