donvitodetroit,
Is this sound loss happening with any other HDMI peripherals? DVD player? Anything else connected to the television?
Could it be that the cable box is sending a 5.1 signal that the AV receiver can't receive?
Keep me posted.

I have lost sound to my HD channels only all others work just fine, started one mont ago on HDMI-1 TV input so I moved over to HDMI-2, the same thing happened today I just lost sound. I have a cable box that connects to my AV reciever than goes out to my tv. Are my HDMI ports going bad? Is there some setting that may have changed? THANKS FOR ALL YOUR HELP.
