Thanks Lee
I'm not sure why something like this hasn't been implemented before.
Lots of machines have multiple sound cards. It seems like a natural
use to want to use one sometimes and another at other times.
As I say, we do it today but it only works, as far as I know, for
applications that support it from the command line. I haven't looked
yet but dong that for something like Firefox isn't optimum as I don't
want to decide that before I open Firefox. It would be nice to do it
on the fly.
Again, thanks

My question is whether Alsa has a user level
mechanism to allow me
in a terminal, on the fly, to switch which card Gnome considers my
default sound card?
I was wondering about flipping a bit somewhere and directing
Internet radio in my browser to the stereo instead of the wimpy PC
speaker we have on my wife's box.
Not currently possible.
I guess to implement this, alsa-lib would have to use inotify to watch
the config files for changes, and the app would register a "sound
device changed" callback that would be invoked when
gnome-sound-properties writes the new .asoundrc. The callback would
have to close and reopen the default PCM and resume playback.
