I have a cheapo Bt878 TV tuner card-- an AITech WaveWatcher TV-PCI. It
cost $10 and it works, so I'm happy. That is, the video works, but so
far the audio doesn't.

I know (or at least, I expect) that I can get the sound to work by
running a patch cable from the sound output of the TV tuner card to one
of the inputs on my sound card. I don't happen to have a patch cable
handy, so I haven't tried this yet. But now I wonder: can I get the TV
audio to play via software, without a hardware connection to the sound
card?

Right now I have the bttv and snd-bt87x drivers inserted. I'm using
ALSA, and in kmix there's an entry for the Bt878 sound card. It has
just one mixer, "Capture" output, which is at full volume. But, I don't
hear anything yet. I've turned on and up all of the input channels on
my sound card, but no luck.

So somehow I need to connect the TV tuner output to the sound card
input, in software. Can anyone help?

Thanks,
Andrew.
