This problem is considerably more involved, and I think several issues are
being confused.
I believe the original post identifies a "problem" with the hotkeys not
controlling the correct card selected in System> Preferences> Sound> default
sound card. This is not a problem per se; I have ICH6 onboard sound, and in
Windows I can't control my external M-Audio Transit's volume using the
'increase' or 'decrease' hotkeys, either. In this regard, I believe this bug is
incorrectly filed against gnome-control-center _unless_ g-c-c has a way of
notifying hotkey-setup to control a different card.
Another issue that has snuck into this discussion is #35540, which deals with
alsa-lib throwing errors when !defaults.ctl.card is not set in
~/.asoundrc.asoundconf. This issue is actually orthogonal to the original post.
The original poster should test with the older Breezy-style "using card indices
in ~/.asoundrc", i.e., ``asoundconf set defaults.pcm.card 1 && asoundconf set
defaults.ctl.card 1''.
The last issue that has crept into this discussion is whether the hotkeys
actually control the proper mixer element ('Master' versus 'PCM'), but luckily
this last case seems moot according to the original poster's testimony.
