Hi J.D. Thank you for your post. Took me a while to go through all possible tests, but the story sounds like this:
All firmware (both denon, panasonic, tv, chromecast) are with latest firmware.
TV via toslink to the AVR - no issues whatsoever.
Bluray (Panasonic) - Set to Bitstream setting
DVD Dolby Digital encoded - no issues, however it seems from time to time the audio is lost. I blamed the cable, so I tested it with 3 different cables, eventually bought new HDMI cable. Issue is...I may say random, so I stick to the cable which gives less issues.
Blu ray DTS-HD encoded - no issues at all with the Resident Evil Retribution - Sound is stable and rich.
In both cases the AVR recognizes correctly the stream and automatically switches to the appropriate decoder.
With the bitstream option set to ON
Netflix - no audio with 5.1 sources, stereo is ok if stream is 2.0. Same with Amazon.
With the bitstream option off and set to PCM
Netflix - converts to 2.0 and there's audio, but it breaks similarly to the one I've experienced with the DVD source.
Amazon - does not recognize the stream encoding, it only shows Multi-channel IN and shows all channels in. (better than netflix for sure, but still ...the audio is pre-processed by the BD Player and converted to PCM).
Note that after playing the DTS movie, I tried Netflix and it took it a while, but eventually it started playing Dolby Digital audio, then after a minute or two, the audio again got lost.
Last option - Chromecast - the chromecast is plugged directly in the AVR and so far have never ever experienced any issue.
NETFLIX - casting to chromecast behaves the same way as from the Panasonic BD player, so I wouldn't blame the Panasonic.
In my point of view - I consider either Netflix to fiddle with the encoding, which is doubtful, or the AVR processors and / or software is crappy.
