So last night I got my Win XP SP3 PC running ITunes to pass audio via HDMI to the Onkyo, along with 1080P video. Looks and sounds great.
The issue now is that the Onkyo does not pass this audio to Zone2, since it is digital.
I have 2 questions:
1) The solution I plan to implement is to use Virtual Audio Cable to clone the ATI HDMI output to the Realtek analog Audio output. With both HDMI and RCA cables plugged into the PC and Onkyo, I should get the same audio in both Zone 1 and 2, just that Zone 1 will be digital and Zone 2 analog, correct? And there will be a slight delay in Zone 2 due to the cloning, which is fine. Is this a good solution, or is there a better solution to clone digital PC audio to an analog port?
2) Just to make sure I understand the DACs... For my signal that arrives via digital HDMI, the audio is being decoded on the Onkyo via the Burr-Brown codecs? In my limited test last night it sounded great. And the analog audio is being decoded on the PC, via whatever codec Itunes is using?
