Hello. Up through this last Friday, my 360 console was connected through my receiver via HDMI. No issues with display or audio. Then this last Saturday no audio via HDMI. I have tried multiple methods of identifying the issue, including verifying correct display and digital audio settings. I cannot identify why audio does not carry over the HDMI cable. I have tested the cable on another system component without issue. I have tried additional HDMI cables on the console, but still no audio. I'm not sure what else I can do. Suggestions? Fixes? I just don't know why audio suddenly decided to cut completely out of a previously satisfactory connection. Thanks in advance.
