How do I downmix 5.1 to 2 Channel Stereo by default?
This never used to be an issue for me but has been for the last few weeks. When playing a 5.1 film or tv episode I am hearing what sounds like only the 'rear' channels. This happens on all of my TVs using an Amazon Fire TV Stick. In particular, movies I have watched previously on these same devices without issue (and all other media presenting the same problem) now require me to force a transcode in order to hear the full audio as stereo. The issue does not present for me in either the Plex Web App, Plex for Windows 10, or Plex Android app.
I have checked the following settings:
Plex App Settings:
Audio Quality - Internet Quality is only available setting to change, not relevant to issue as content is on local network.
Advanced - Audio Passthrough - Tried both 'Off' and 'Auto' with no change in issue.
Display & Sound - Audio - Dolby Digital Output - Tried "Dolby Digital Plus Off" and "Dolby Digital Plus Automatic" and neither eliminates issue.
I don't know where else there are relevant settings to be adjusted. Any suggestions, or known fixes, appreciated.
