I haven't posted in a while, but I know that you guys are good, and can lead me in the right direction!
I have...
Denon 3805
Panasonic 50" Plasma
Sony upscaling DVD
Axiom M80s, EP500, VP150

From the DVD player, I'm running HDMI to the TV and digital optical to the Denon. At one time this was working great - beautiful and booming sound, and a terrific picture! Somewhere along the line, I guess I tweaked something and there is no sound.

I've tried adjusting the setup on the Denon, but can't seem to find the right tweak to get me back to movie happiness. I also switched out the digital optical to digital coax in case the optical cable had been tweaked -- no help.

Any suggestions?? I know the fix is likely something simple, but its eluded me...

Thanks -
