[Pkg-alsa-devel] Bug#244068: alsa-base: force-stop option doesn't work properly

[Richard Black]

Package: alsa-base
Version: 1.0.4-1
Severity: normal


When a proc is using the sound option, and $ALSA_KILL_MODE" = force, the script /etc/inid.d 
trys to execute:

		if [ "$ALSA_KILL_MODE" = force ]; then
		    printf "(terminating processes) "
		    kill $procs_using_sound
		    sleep 2
		    kill -9 $procs_using_sound
		else
		    printf "aborting. (sound used by PIDs %s)\n" "$procs_using_sound"
		    exit 1
		fi

after which the modules should be removed.

The problem seems be that if the first kill is successful, the second kill gives
the following error:

Shutting down ALSA (version 1.0.2c): (terminating processes) ./alsa: line 146: kill: (11694) - No such process

....and so /etc/alsa exits.  This implies that the modules are not removed, and in my case this means
no sound when they are restarted.

As background, I seem to need my modules to be unloaded and loaded when I suspend my
laptop.  The above problem stops them being unloaded.

cheers
