What do you think of the tolerances around the unit?

The pictures great but the sound isn't working well at all. The sound plays on the (much nicer) TV speaker. But it also plays on the tinny, shoddy laptop speakers as well. I can't find anyway to fix this. The computer only shows one playback device. The driver is fully updated according to the device manager and I can't think of what else to do so. Anybody had success getting audio out who can share some wisdom? Thanks.
