Hi Phil.

If you're talking about DVB tuners then yes, the sound is part of the 
MPEG stream and therefore does not need to be connected to a soundcard. 
  As far as I know there isn't a single digital TV tuner card which 
requires a connection to a soundcard for digital TV reception.

This only applies to digital TV - if you want to record analogue video, 
say from a set top box or vcr, then you'll need to use the svideo or 
composite connections and plug an audio source into your soundcard.

Regards,
Justin.
