I want to get a small(13in.) TV for my office just off the H-T room. Problem is these little TV's have tiny speakers-you know how they sound! I want to use outboard speakers to improve the sound, so will bring a video feed to the office receiver/amp by coming out of the H-T Direct TV receiver, using coax. But none of the little TV's seem to have audio out with which to feed a receiver to power speakers in the office. Is there a way to do this?
