I am using one ATI TV Wonder VE capture card which has a composite and a coaxial input. I am currently subscribed to DirecTv as well as my local cable company.

I've managed to set up the DirecTv video feed into the composite in and sound from the receiver (via RCA plugs to stereo mini plug) going into the onboard sound line in.

The local cable feed is going into the coaxial input on the same capture card with the audio coming out of the capture card and into the onboard mic in.

This set up works fine for video. Myth can change channels on either source (DTV via serial control) and record.

How can I enable the mic in for the cable feed? Is it possible? When running mythtv-setup, it seems that the audio device is tied to the capture card and not to individual inputs. Perhaps I'm overlooking something, but I can't see how to set this ....

BTW, the TV Wonder VE does not have bttaudio, so that's not an option
