Look in your audio output settings(receiver) for LPCM OR PCM, and see if you have a setting for (96khz)...or other setting, that might change the output for audio.
Hope I am not stepping on a thread here; but this is a question of interest to me, as I begin preparations for HD. I have a Denon AVR-589 Receiver. In the audio set-up..... under LPCM(output) there is a selection for 96khz and 48khz. I am wondering if this setting might change the output of audio, in some way(passing it through, instead of processing it) or redirecting the digital audio to coax or optical outputs? This might make the HDMI audio signal, bypass the receiver; or require optical/coax connections. Just a thought. Don't count out an audio setting. I have seen in various posts, on my receiver, that it does not process the HDMI audio signal; and needed the Optical or coax, to get HD sound. When I go to the Manuals in several locations; it does not indicate any limitations on the receiver processing the HDMI audio signal; only that the TV audio needed to be turned down. It also mentioned no audio through receiver HDMI, if you are using a DIV cable to the TV, instead of an HDMI. My manual, also says that I have a DTS 96khz processor. Hope this gives some direction, interested to know if it could be an audio setting.I don't have my HDMI input device(Blu Ray)yet; but contemplating this issue now. I am betting on this setting.
I have also read that the DTS(Digital theater sound) 96(KHZ)processor is able to process Blu-Ray Audio.......and that both DTS and True HD sound processors, are loss-less formats. Anyone know about these formats? Am I getting full Blu-Ray sound capability, from a 96khz processor, and setting?
