Welp, feeling a bit overwhelmed and discouraged at this point. Between the guide and examples I think I have enough of a grasp on how it should look, even if I feel a bit out of my depth.
However, I haven’t had any success in tracking down what file formats are supported by my TV (some manufacturers list them, others do not) and I don’t want to break any existing functionality or make things worse. I just want to disable Opus.
I could start randomly trying other XML files that I have found, but that feels very trial and error and not something I really want to waste time on.
I also found posts by @sixones “Changing the Android.xml profile has no impact on the Android client” https://www.reddit.com/r/PleX/comments/wnw8nn/disable_direct_play_on_android/ and @OttoKerner “there is no need to mess around with device profiles nowadays.” https://forums.plex.tv/t/client-profiles-still-relevant/849312/4 that seem to indicate that there is nothing to be gained from this route anyway.
And someone from a year ago who seemed to be experiencing the exact same issue and seeking the same solution, but without any support, follow-up or resolution: https://www.reddit.com/r/PleX/comments/xrnvln/why_wont_pms_transcode_to_literally_anything_else/
So I feel like my options are:
- Trail and error with XML
- Try Kodi on Google TV
- Resort to using Xbox
- Try Jellyfin and Emby (have been meaning to anyway)
- Hope a Plex update fixes things
- Return this TV and go back to my old one, or get a different one (but Black Friday and Boxing Day are now over). Plus this TV is a definite upgrade, it’s just this annoying issue.
Not really enthused about any to be honest. I just want Plex to consistently choose EAC3 and never Opus, instead of randomly one or the other
