i really doubt it - as no audio grabbing code in the tvi_v4l driver :)
it may grab something (random data or silence or dunno what) but i doubt it
come from /dev/dsp

maybe your card produce some audio via the v4l device?
afair alex started some work on that long time ago, but never finished, and
no a-v sync code at all...
