I never knew this was such a big problem. I assume you are talking about the audio portion of HDMI. I've been using HDMI, video only to TV's and computer monitors with no issues.
Receiver HDMI problem
Have a Marantz 7008 for which I already had HDMI board serviced. Running 35' HDMI cable to projector. Connected to Marantz is cable box and Apple TV.
Situation: HDMI cable from Apple TV directly to projector no problem everything works normally.
2) HDMI directly from cable box to projector = no signal
3) Connect 35' HDMI cable from projector to receiver = no signal from cable box or Apple TV Called Marantz told me to use booster so bought a Gefen Superbooster plus. Still no signal.
Everything points to long run cable problem except how come connecting long run from Apple TV to projector works but not directly from cable box (2). ???
What's going on and how do I fix this?
Thank you. Tom
