i do not know when this started but i know i used to be able to play AC3 5.1 audio with my roku premire+. my setup is as follows: Plex server 188.8.131.5248 running on qnap / roku premiere+ running 7.5.1 build 4100-29 connected to vizio P55-c1 tv sound goes to the receiver via optical.
if i cast to it, using the tv built in app, i get sound jsut fine. but the plex app on the roku does not give me any sound
