Audio Output Format Settings Confusion
I am still struggling trying to understand how the Audio Output Format settings work. What is the relationship between Audio Output Format and Audio Output Format (Optical). Did something change recently? Last week the two settings appeared independent, this week it appears that Audio Output Format has some effect on the Optical setting.
Even though I do not have a 4K TV I bought the Ultra HD/BluRay combo of Wonderwoman and played the UltraHD version as an experiment. According to my receiver, the feature audio was in Dolby Prologic II! I went to settings... Audio was set to Auto and Optical was set to Bitstream (Unprocessed). Last week that seemed to allow my receiver to play DTS or Dolby, which ever the disc was formatted for. Now I could not change the Optical setting, I could select something else, but it would stay in Bitstream (Unprocessed). I then changed the Audio to Bitstream (Re-encode Dolby D) and the Optical automatically switched to that as well and was grayed out so I could not select it all.
I set Audio Output Format to Bitstream (Unprocessed), which automatically set Audio Output Format (Optical) to Bitstream (Unprocessed). When I played Wonderwoman Ultra HD it played Dolby Digital. When I inserted Pacific Rim and Fantastic Beasts Blu Ray it played DTS, and when I played an older Blu Ray in Dolby Digital, it played Dolby Digital.
To use the Optical Digital Audio ouput and play the format the disc is encoded in, seems to require setting the Audio Format to Bitstream (Unprocessed), which automatically forces the Optical setting to that. Despite a whole page describing how the modes and formats work together, the manual is not clear how the two settings work together, and at this point I am not sure why there is even a separate Optical Digital Audio Format Setting. It is either set automatically or ignored.
