BenH2,
I have the Oppo Sacd option set to PCM and multi channel and it comes through the Hdmi. Sounds really good. Same with DVD-audio. Only need the analog for my old DTSCDs.
When I try that, SACDs in 3.0 or 4.0 format do not play in the right channels. 3.0 plays in L/R/SR speakers - should be L/C/R and 4.0 sound is from L/C/R instead of L/R/SL/SR. Not totally sure if 5.1 are decoded correctly but I think so. Sound is from correct channels using analog 7.1.
Waiting for Oppo response.
