Multi-seated machine.

Multi-seated machine.

[James Courtier-Dutton]

Hi,

As linux can now be used in a mode whereby one has one base box, and 
then multiple keyboard/mouse/screen, how might one separate the sound?
I.e. Sound card 0 for screen 0, sound card 1 for screen 1 etc.
Or one might want "Front" for screen 0, "Rear" for screen 1 etc.

How would we achieve this in ALSA?
I expect we would need a different asoundrc for each screen, but I don't 
know how well this might work or not.

Is this possible OOTB on any distro?  Last I heard it required kernel
and/or X patches?  Got a link?

AFAICT it should work now with Gnome and multiple soundcards as long as
each screen logs in as a separate user - gnome-soundcard-properties just
modifies the .asoundrc to set the default soundcard.  If Gnome could be
made aware of this multiple-console-user mode then it seems like it
could be made plug and play...

With a single soundcard it seems like it would be very tricky and
hardware-dependent, because Front and Rear are not independent on most
devices?
