How to Play Two Audio streams to two different outputs?

[Kent West <westk@acu.edu>]

We're wanting to use one Debian box to play two different audio streams 
to two different systems: one playing music-on-hold for our general 
telephone system, and one playing tips-and-updates for our Helpdesk 
phone system (for simplification purposes, you can just think of the two 
streams going to two different sets of speakers located in two different 
rooms).

I figure we'll need two sound cards, each driving its own set of speakers.

But how do I get the system to play one audio stream on one sound card, 
and a different audio stream on a different card, at the same time?

Running two different apps (or even the same app) under two different 
users is not a problem; I just need the audio to not mix between the two 
outputs.

Thanks!
