(Dropping Importance. Sorry, but a usability bug, while extremely
annoying, does not constitute an Importance of the extremity of a system
crash.)
If System> Preferences> Sound> Default sound card's drop-down menu is
not working properly, that's a bug in the gnome-control-center source
package.
alsa-utils in Dapper includes the asoundconf(1) utility that gnome-
control-center's Sound applet invokes to perform the background task. If
you find using asoundconf(1) [see the set-default-card convenience
macro] remains utterly ineffectual, then you can forcibly set one driver
to /not/ be the default (i.e., not grab index 0).
Let's take the example of my computer, which uses the snd_intel8x0 and
snd_usb_audio drivers. (While asoundconf(1) works for me, for the
purposes of this illustration I'll pretend it doesn't work.) Let's say
that I really want my onboard sound chipset to be the secondary instead
of the primary, since my M-Audio Transit USB is a "much
better"/preferable device. In this case I would issue the following
command:
$ echo "options snd_intel8x0 index=-2" |sudo tee -a /etc/modprobe.d
/alsa-base
The above command effectively forces the snd_intel8x0 driver to not grab
the first available index in the presence of other drivers.
So -- what info is needed for you guys? Please /attach/ (don't comment
inline) the output from ``lspci -v && cat /proc/asound/cards''. Also
indicate which of the cards you wish to use as the primary one and
whether asoundconf(1) [with the convenience macro mentioned above] works
when you invoke it by hand and restart ALSA apps (this does not affect
OSS emulation).
