Hi. My memory isn't what it once was and I'm sure I should know this but... Having gone through manuals for both devices, my BD player tells me to set audio through HDMI to 'Auto' rather than PCM, which I have done, but, having set up my AVR as I think it should be, Both the player and AVR are displaying DTS-HD, or Dolby True HD etc, and I just want to know which device is decoding what into what? Nothing says 'bitstream' anywhere and I believe that the AVR should be doing all the decoding. Why I have this problem is, a few years ago, my then receiver had six analogue inputs that I put through from my Sony DVD, so that I could get 'proper' Dolby/DTS sound through and it was obvious just what was doing what. When I then upgraded both devices, the BD-Player then had bitstream coming through and it shew on the display that the AVR was doing all the decoding. Now however, (having had to change a broken player for an older one that still works), I have a Sony BDP-3500, feeding into a Denon AVR-X3300W. The player like I say, shows Dolby or DTS on it's display, suggesting that it is decoding, but then the AVR is also showing the format on it's display! I would prefer the AVR to decode everything. Sorry that this is a bit repetitive, but I'm just frustrated that it's seemingly impossible to find out exactly which device is doing the decoding and if it's wrong, how can I change it? Many thanks for any help given.
