Okay, I've spent two days looking around various AV forums trying to find a definitive-ish answer to a sound configuration question I now have. I've gotten more confused (rather than less), so maybe I can get a good answer here. I have a Panasonic BD35 connected by HDMI 1.3 to an Onkyo HTS6100 (Onkyo HT-S6100 - 7.1-Channel Home Theater Package with iPod® Dock | Model Information | Onkyo USA Home Theater Products. I popped in the new Star Trek:TMP blu-ray yesterday and noticed no sound at all with the menus or trailers. I spent a few minutes checking out settings and noticed I have the Panny configured for BITSTREAM, with BD Secondary OFF. I switched to PCM with Secondary ON, and now everything seems to be working. But since I'm not seeing the 'True HD' marker on the Onkyo display with PCM, I'm wondering if I'm sacrificing something with the PCM setting. I see something called 'PCM multichannel'. I wouldn't mind the lack of menu audio to keep BITSTREAM if that's the only way I can hold on to the lossless track, but if there are features and trailers that won't have audio as well, this is likely going to bug me, and I'm not keen on switching all the time. So, what does everyone here do? Is PCM/secondary ON retaining the lossless tracks as some information says, or am I losing something (like other sites/posts seem to suggest)? Is there another suggestion on how to configure things to keep both features? Thanx in advance for your help with a question I'm sure has been brought up before.
