I don't understand why the issue of needing a dongle for audio keeps coming up. 90% of HDMI capable TV's provide an optical and/or digital output to provide 5.1 from an HDMI source.
A lot of people like myself would rather just connect the audio directly to the receiver instead of adding a middle man. That way all my OAB are 2-channel output and my 360/DVD output is optical. Keeps me from having to keep changing my audio source on the receiver every time I change the input.
