Package: gnome-control-center
Version: 1:2.22.1-1
Severity: normal
I have a machine with two sound cards - the integrated one and an external
studio-grade one.
The gnome-sound-properties component of gnome-control-center allowed me
to see the sound cards by a descriptive name, e.g "RME Hammerfall" rather
than the ALSA hardware name (e.g. hw:0) and choose which one I wanted to use
for which type of application which I did, choosing the studio card for the
category "Music & Movies".
Some time later I rebuilt the kernel and, after doing this, the wrong
sound card was being used for playing music. When I opened
gnome-sound-properties a second time to check what was going on each
of the drop down lists for the various categories had the same descriptive
names selected as when I has last closed it but in each case with
'(not connected)' after the name.
Clicking on each drop down list and re-chosing the sound card I want seemed
to solve the problem and sound now plays on the correct card.
My suspicion is that re-building the kernel changed the order in which the
cards were found at boot time and therefore which card was hw:0 and which
was hw:1, that gnome-sound-properties had saved the hw:0 style ALSA name
with my preference and that the not connected message meant that ALSA no
longer reported the same descriptive name against that hw:0 style name.
Obviously it is the particular card I want to pick in the preferences
and not an index into the list of sound cards found at boot. It would be
better if the descriptive name offered in the drop down list was all that
was saved as my preference and that some daemon queried the list of cards
from ALSA when GNOME was stared and maybe also listened to hotplug events
to establish the correspondance between descriptive names and hardware names.
