I recently received a refurbished US Tivo and I have been experiencing the wonders of PVR technology at it's finest. Only problem is I can't get a sound signal. I can play back sound fine. Intro and menu noises are there. But when trying to receive a sound signal from my cable box, a sky decoder or any other sound source, it's a no go. Needless to say I'm pretty dissapointed as the company I bought it from assured me it would be tested before delivery. And of course I couldn't get a warranty.

Before I look at alternatives, including buying another unit, I thought I would ask around to see if anyone has any ideas. Unless I've missed something in my extensive search it looks like I have faulty hardware. What options do I have?
