So you'd have /dev/dsp1 and /dev/dsp2. I don't use the apps you mention but there's no reason why it would be difficult to switch between sound cards because coding it would be no more difficult than writing to 2 different files. If you wanted to play 2 different sound files at the same time you could just do this: # cat file1.au > /dev/dsp1 # cat file2.au > /dev/dsp2 Anyway, I guess my point is that if it is difficult to switch between sound cards the application is bogus. ----- Original Message ----- From: "Gregory Nowak" To: Sent: Wednesday, November 01, 2006 12:13 AM Subject: multiple soundcards > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Hi all. > > Is there anyone here using multiple soundcards with alsa?
