 playing through the two stereo speakers. The initial submitter's problem
 is probably solved by using the "surround71" device instead of hw:0, but I
 failed to figure out how to use something like that with multiple sound
 cards. I eg. do have three cards in my box and would like to be able to
 use any of them for multichannel output, not only the first one. Any hints
 for that?

 card or just a pair (e.g. front).Mine (audigy) has 4 seperate hw files
 (hw:0,0 hw:0,1 hw:0,2 hw:0,3) each bound to a stereo pair.

 I *really* have three surround-capable sound cards. "surround71" just
 addresses the first one, but up to now, I fail to find out how to access
 something like "surround71" on hw:1 or hw:2 instead of hw:0.

 In your mentioned case, with several stereo channels that need a combine
 to bring up a "complete" surround card, I'd already know how to do that
 :-)
