I just switched to the Roku in my TV (which I never use, as I use an ATV), and it seems to work fine on the latest version. No audio sync issues for me!
well, if you notice what it is, let me know, and I’ll try to reproduce it. also, try dumping your Plex logs into a pastebin, and link it here. I’ll try taking a look.
set log level to “Debug” in serve settings and play something where the audio lags.
