Hi there, I've scoured Google and have no where else to turn. My house's Sony receiver will not output sound over HDMI. I get picture just fine, but there's no sound. Currently my workaround when playing media off of a laptop is to use a Y-cable into Video 2 and a VGA cable directly into my Mitsubishi HC3800 projector (bypassing the receiver). This works well enough, but it's very inelegant and of poorer quality. Analog output works fine with audio and video. There is also no sound when hooked up to my HD tuner. The HDMI cable is 1.3 category 2 rated. I've tried changing the HDMI AUDIO OUT setting to TV+AMP and AMP but to no avail. I also notice the speaker indicator lights on the receiver's LCD panel light up for the other input selections (Video 1, Video 2, BD, SAT, etc.) but not for the four HDMI inputs. Can someone help me? I've been troubleshooting this for hours. Thank you for your help!
