[Pkg-alsa-devel] Bug#527074: /etc/init.d/alsa-utils: `/etc/init.d/alsa-utils stop` triggers amixer error

[Piotr Lewandowski]

Package: alsa-utils
Version: 1.0.19-2
Severity: minor
File: /etc/init.d/alsa-utils

#v+
$ sudo /etc/init.d/alsa-utils stop
Shutting down ALSA...amixer: Invalid command!
done.
#v-

It is caused by `mute_and_zero_level` function in /etc/init.d/alsa-utils 
which invokes: `amixer -c 0 -q set Mic 0% mute`.

Additional output from lspci:
