Using the three HDMI 2 in one out I am not getting TV sound or DVD from A/V. Have 622 Dishnetwork DVR with it's out HDMI going to one in on A/V,DVD HDMI going to other and HDMI monitor out to Sharp HD Aquos. Picture and sound great on Sharp but can't get sound from receiver, just radio.
Sorry, that should read "owner's manuals". If you have no sound other than tuner from the receiver, you should begin there but you might have to flip a few switches in the various source components menus to get everything working.
