I have lost my audio streaming from my pc to my Marantz SR500r receiver using hmdi cables. I still get the video. If I connect directly from my pc using hmdi directly to my tv I get both video and audio on my tv speakers. I have tried to use different hmdi ports on my receiver but the results are always the same. When I run my dvd through hmdi cables through the Marantz I get video and audio. I tried to connect my pc to the dvd hdmi on my Marantz but I still get no audio. I have spend hours over the phone with the Best Buy Geek squad but nothing has changed. I am thinking about buying a new receiver at this point as I have tried most things but no change.
