While watching TV last night the sound on my 1070 suddenly stopped, as if someone hit the mute button. Of course the first thing I checked was the mute button. Now I have no sound at all, nothing on DirecTV, DVD, CD, X-Box or GameCube. I've checked to make sure all inputs are configured properly (they are). I tried analog connections on DirecTV and DVD, still no sound. This morning I did the firmware update hoping that may correct the problem, it didn't. I've also performed the system reset outlined in the manual. Any suggestions or do I need to ship this thing back? Perfect timing, BTW, now that we are in playoff season.
