Yes, this works. I have a Hauppauge card with coax, S-Video
and composite. There is an internal patch cable from the
tuner card to AUX on the sound card. Cable is attached to
the coax input. A digital cable box is connected to the
S-Video input. Audio from the digital cable box (2 RCA to
mini-phono jack) is conncted to the line "In" on the tuner
card.

When I Watch TV, I get audio and video from the coax. When
I press "c", it switches to audio and video from the digital
cable box (S-Video and RCA audio). ALSA capture is always AUX.

When I first used the S-Video, I connected audio to another
input in the sound card. To switch, I would need to change the
ALSA "CAPTUR" selection (not mute/unmute). However, having one
input from the tuner card and letting the tuner card switch
the audio is much easier.
