[Pkg-alsa-devel] Bug#625233: alsa-base: alsa force-unload

[Torquil Macdonald Sørensen]

Package: alsa-base
Version: 1.0.23+dfsg-3
Severity: normal

I'm not sure if this is a Debian or upstream bug, because I don't
know if the script /usr/sbin/alsa is Debian specific or from
upstream. But here goes anyway:

The command "alsa force-unload" fails to kill the running process
xfce4-volumed that is using /dev/snd/controlC1. Looking at
/usr/sbin/alsa, it only kills processes that uses /dev/snd/pcm*. It
seems that this is not enough?

The result is that the "modprobe -r" command run later by the script
fails. If I kill xfce4-volumed manually, "alsa force-unload" fails
on the first execution, but then running it again removes all the
snd_* modules. Could that last problem (need to run twice) arise
because it tries to remove in the wrong order?

I'll check once more if the first execution of alsa force-unload
has any effect on the list of modules, and report back here.

Sory about the /dev/snd listing that is supposed to be in this
bug report. I'm writing it after having removed the modules. If it
is important, I'll include it in a follow-up.

Best regards
Torquil Sørensen
