postinst fails: /proc/asound/cardconfigure/id doesn't exist

[Moritz Naumann]

Binary package hint: alsa-utils

The alsa-utils post installation script fails for me.

After adding "set -x" to the 4th line of /var/lib/dpkg/info/alsa-utils.postinst I get:

# dpkg --configure -a
Setting up alsa-utils (1.0.23-2ubuntu3.3) ...
+ S=/etc/modprobe.d/sound
+ [ -f /etc/modprobe.d/sound ]
+ dpkg --compare-versions 1.0.23-2ubuntu3.2 le 1.0.23-2ubuntu3.3
+ cat /proc/asound/cardconfigure/id
+ id=
dpkg: error processing alsa-utils (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 alsa-utils
#

As to be expected:
# stat /proc/asound/cardconfigure/id
stat: cannot stat `/proc/asound/cardconfigure/id': No such file or directory
#

Assuming that $1 would contain the ALSA card ID here seems wrong, since this $1 is cleary the "configure" argument to the postinst script in this context. Instead the thing to do here is, I assume, for each ALSA card, to check whether it is a "Panda" or "SDP4430" and (only) for every one that is, to execute "alsactl init <card ID>". Patch attached.

Sorry, scratch that first patch, it was buggy, too. This one actually works now. But since this bug is already fixed in #664645 this is just to correct my earlier mistake.
