Maybe you should ask on the ALSA list, as this isn't a MythTV problem..

? Not sure what you're trying to do here. Why would you mute xawtv? Why
would you 'aplay /dev/dsp', when /dev/dsp is the sound card output
device?

You need to make sure that the right line-in device is selected as the
recording input AND has some input gain, for recording (with MythTV). To 
hear it with xawtv, you need to make sure it has some playback gain.
(However when watching Myth, you'll want to turn the recording gain to
zero.)
