"Normal" Dolby Digital and DTS are fine, it just seems to be the "HD" variants... I browsed through this (and other) forums and learned to switch the Blu-Ray player HDMI output from "bitstream" to "PCM", and that did get the audio working for the HD formats, but my father is concerned there is something wrong with the AVR he just purchased...
Is there no way to get the Denon to properly decode bitstreamed HD audio? Sorry if this has been answered before... I tried the search engine and didn't get anything relevant.
One thing I forgot to mention: while the Panny Blu-Ray has had a firmware update, I haven't been able to connect the AVR-1713 to the internet in order to check if it needs one... Possibly, but this HD audio support is advertised on the box, so I'm pretty sure it should work "out of the box".
Can someone please help me out? I'm brand new to home theatre setup (I'm a 2.0 guy), and I'd like to get this resolved, as my dad wants to return the 1713.
Did you not see JD's post addressing your question immediately after you posted?
The key thing to understand is that it's NOT the receiver, it's the SOURCE. The receiver can only play what it gets -- there is no setting to "activate" the hi-def audio on the receiver. If it gets it, it will decode it and you will see it register on the display.
What is happening is that the Blu-ray player (because of the way its settings are configured) is decoding the HD audio and passing it out as multichannel PCM.
You can always confirm the input signal by going into the GUI and then selecting General > Information > Audio. Also, if you are receiving a multichannel signal, any of the surround mode buttons (Movie, Music, etc) will default to the "standard" decoding of that signal. So if you press the "Movie" button and it says "MultiCH IN" then you are getting multich PCM as the input... if you press it and you get "Dolby Digital" then you are getting Dolby Digital, etc.
So, back to JD's post..... the likeliest cause of the Blu-ray player refusing to output the bitstream HD audio is that the "secondary audio" setting is ON. The secondary audio refers to things like special features, director's commentary, etc. and the Blu-ray player must decode the audio to PCM in order to mix in the overlay audio.... so even if you have the BDP set to "bitstream", when you have secondary audio enabled it will decode anyway in anticipation of having to mix in additional audio. By setting it back to "bitstream" for HDMI audio and turning off HD audio, you should be able to get the HD audio to bitstream. You will know it's working because the receiver will say "Dolby TrueHD" or "DTS-Master" when you hit the "Movie" button.
Also remember to actually select the correct audio track on the Blu-ray, because it's not always the default.
Anyway, you can also remind your dad that the decoded PCM audio is identical to the bitstream audio, so even if he gets multich PCM (e.g. you leave the secondary audio settting ON because he likes to listen to the director's commentary) he is NOT losing out on any audio quality.
