No Sharp Aquos Digital Audio Out

Have you tried another cable.

try turning off "Dolby 5.1 output" in Settings --> Audio

I have the same problem but with the Mac mini - I connected the mini with DVI to HDMI cable into Input 6 [on Sharp Aquos LC-46SE94U] - connected audio from the headphone jack to a splitter into the red and white inputs associated with the hdmi input resulting in no sound through the TV speakers. When I connect the same cable to external speakers (bose) I get sound.

Picture is great - no sound is a problem. Any thoughts?

Same problem with my Sharp Aquos. I've also tried differente settings and cables with no luck.

Go into the menu of the sharp, over to audio (or sound) and turn off HDMI audio. This should make the TV default to analog audio for that input. Or you may have to tell the sharp you using a DVI cable in the video menu which would make the TV default to the correct audio input. If this doesn't work try a different brand 3.5mm to RCA adaptor.

I have the same problem with my LC 46D-64U. The digital output works with all my other devices. Tried all possible settings, unplugged and reconnected without any luck.
