HDMI on panny SA-XR70

Has anyone given the HDMI input on the panasonic SA-XR70 a try ? It would be very nice if all six channels could be hooked up to a PC using true digital transmission (im thinking using the digital xover stuff in foobar etc. for a 3way system).

The questions remain:
- are there anyway to get HDMI sound from PC to a receiver ?
- can the 6 channels in the panny be feed using PCM data from the HDMI input (i.e. is it all 6 channels and is DTS or AC3 needed)

A HDMI soundcard and the panny could be a speaker tweakers dream :D
 
motherone, I think you must be mistaken. From the link you sent:
Supports compressed audio formats such as Dolby Digital, Dolby Digital EX, DTS, DTS EX.. Driven by the DVD-Audio standard, audio support consists of 1-8 uncompressed audio streams with a sample rate of up to 48, 96 or 192 kHz, depending on the video format. It can alternately carry a compressed multi-channel audio stream at sample rates up to 192 kHz, up to 24-bits.

Now, the Panny may well not support uncompressed-over-HDMI, but the spec seems to.
