Since you asked 8-),

1) Both sound cards must be a different chip set. For my setup, I am using the 
built in MB sound - : VT82C686 [Apollo Super AC97/Audio] and a SB compatable 
- : CT5880

2) Each sound card need a different IRQ and control register addresses - The 
IRQ is taken care of at the BIOS level (MB) and the chipsets should 
automatically map out differently. At least they did for me.

3) Once you boot Mandrake, run the MCC (Mandrake Control Center) and verify 
that the sound cards are using different drivers. Then run KMIX and verify 
that you see two different Mixers available.

4) Now this next step can be the tough one. The programs should allow one to 
set the default sound card, thus allowing you to route the audio to the 
appropriate card. XMMS is a very nice program, but it ASSUMES that only one 
sound card is available. So, it will automatically select sound card 0. 
Fortunately for me, the SSTV program allows one to set the sound card, so I 
have it mapped to sound card 1.

5) Lastly, ARTS is turned off and I "renice" the more important program.
