[PD] Routing from tuner card into PD.

[B. Bogart]

ARG!!!!!!

That did it.

Damn, I would have never even considered that both those channels would
need to be marked.

So now I can get my tuner sound into PD!! woo hoo!

Thanks Claude.

I'm glad I don't have to buy a new soundcard just to do this part!
