I have an old bt848 based sound card. It's a TurboTV from IMS/ixmicro, originally marketed to Mac users. I got it to work with KM. I don't recall offhand which config settings I used though. Also I didn't try to use btaudio yet; it's still using a patch cable to the sound input.

My question... Can anyone tell me for certain if this thing can capture stereo sound? I remember with my PowerTower Pro and bundled software it could only do mono sound, and the resolution wasn't so great. But that could've been an issue with how little processing power computers had back then.

Here are more details about this card. I copied this from the card itself, so I can't be sure that it all means anything.
