I have a Marantz SR9600 and it doesn't seem to accept a 7.1 pcm signal over hdmi. I had the firmware upgraded to the latest version, and it did not seem to help. My SR 9600 is a U1B (version?) and does not have the Sirius SAT radio capability. I spoke to somebody at Marantz Technical Support and he mentioned that they had an upgrade about 1/2 way through production. I have not found out anything else.
If you have an SR9600 and a Blu-Ray player which has internal HD audio decoding, you can send 7.1 pcm over hdmi to your receiver. I'd like to know if your SR9600 receiver can accept this signal, and which version of the SR9600 you have. I briefly had an SR5002 and SR8001 and they were both able to accept and play back a 7.1 DTS-HD signal that was decoded and sent ala pcm signal over hdmi. The channels lit up on the front display and the rear surrounds play audio. With my SR9600, I don't recall getting all channels to light up, and while it says "7.1 pcm multi-channel" on the 5002 and 8001, it doesn't say this on the SR9600, and there is no audio in the rear surround speakers.
thanks in advance for feedback from SR9600 owners,
