Well, I have the same receiver. Unfortunately there is no audio decoding in any form with the HDMI connections, it was meant for just an HDMI pass trough or switching. The only way that you are going to get the best quality audio is if you use Fiber Optic cable from Monster Cable. You would have to interconnect the Fiber Optic cable from your device to the receiver ports. Then just send an independent HDMI cable from your device to your Plasma HDMI ports. That's how I have my receiver hooked up, and it sounds great. But you may need to upgrade you receiver to one that is capable of decoding Dolby TrueHD and dts HD. Possibly a Pioneer or a Denon. In-store associates may help you in choose the best receiver for and your needs.
