Yeah, aplay -f dat /dev/video24 plays the TV audio without a problem.
This is what I get through ivtv-radio:
[mythtv at mythtv ~]$ ivtv-radio -f 95.5
set to freq 95.50
Running: aplay -f dat < /dev/video24
Playing raw data 'stdin' : Signed 16 bit Little Endian, Rate 48000
Starts off with a low rumbling noise, then changes to a normal "I
can't get anything on this frequency" noise.
