The TV Wonder Pro uses the cx8800 module (and chipset), so 
unfortunately, there's no btaudio equivalent. dsp and dsp1 are a matched 
pair of Soundblaster Live OEM cards that I liberated from some junked 
machines.

The mystery gets deeper, though. Despite the fact that I'm running udev 
and getting the proper entries, and /proc/asound says that the second 
Live card is ALSA card 1, and the fact that I can mix the card with 
alsamixer -c 1, I'm still not getting audio in or out of it.

Is anyone else out there running a dual sound card setup with two tuners 
and two patch cables? Especially on debian?
