Well, I’ve run into a problem.
Whenever I need surround sound (on the primairy aTV), I need to edit the PlexAPI and either replace the iOS with tvOS or add your Client-Profile-Extra. But when I do this the second aTV will not play media anymore.
On the second aTV I have a working connection, I can browse libraries and select media and even subs and audiotracks within those videos. But when I select play I only shows the very first frame of that video.
I can see PMS converting the file, cpu usage is consistent with a file being played. Also I can skip ahead in the video (aTV remote for iPhone lets me skip 10 seconds at a time) and then then the TV displays that one frame. But no video playback.
Once I restore the original PlexAPI (with ‘iOS’) script the video displays without any problem.
Any idea? I could build a second PMS/PlexConnect for stereo only and mount the same CIFS shares, but that seems overdone.
