On android based devices you can’t direct play Hevc video.
Stereo FLAC and Stereo AAC audio without changing the video resolution to something lower and then back to original quality to get plex to direct play the damn’d audio.
I’ve managed to make a ghetto xml profile that works for flac but I haven’t had any luck getting AAC to not transcode. Due to whatever transcoding settings with OPUS the audio loudly pops whenever seeking.
edit: may have bumbled my way into getting aac to not transcode by editing either the universal mobile or tv profile…
