I am running Ubuntu 8.04 with two sound cards. below is the lspci for the sound cards

00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)

06:03.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07)

I currently have it set up so that my normal sound comes through the Creative Sound Blaster, and all my applications I am using wine for use the Intel. I would like to make it so that I could run my Music (rhythmbox) on the Sound Blaster, and VLC Media player on the Intel (or any other program). If any one knows of a good mixer that will allow specific applications to use a certain sound card, that would work. Or if anyone is willing to help me write a program to do it (i am not a good enough programmer to do this on my own yet) i would really appriciate it.

Thanks,

don't know if it would work or not, but look at jack and qjackctl
