Using the most recent version of PSM and the most recent shield plex app as of 03/01/2022 9AM EST.
Basically I have 3 nvidia shields, two hooked up to modern 4k dolby vision/lossless audio supporting avrs, and one hooked up to a 4k tv in my bedroom that is hooked up to an older 1080p avr via arc. When i play a file with dolby digital/dts surround sound it works fine gives me the 5.1 audio i want, but I when i play a video that has flac(which i convert my non atmos/dtsx tracks to to save space)/pcm 5.1 yeah it doesnt work it just gets down mixed(I assume by the shield) to pcm 5.1.
The plex dash shows me as direct playing the flac/pcm 5.1 audio so thats just getting passed to the shield as is. Is there a way I can just make plex transcode the flac audio to dolby digital 5.1 for just that one shield in my bedroom and leave it alone for the other two?
