can't play 5.1 channels on Plex (but can on other channels)
I have been successfully playing 5.1 channels with Plex on my Roku (2019 Ultra) without issue, but I can now stream only 2 channels. I have checked Roku and Plex settings, switched HDMI cables, uninstalled and reinstalled Plex, and confirmed the problem with several movies. These movies do have a 5.1 channel track, as confirmed by Stream settings as well as by playing the movie(s) with VLC on my Mac (which is also connected to my A/V receiver). I can get 5.1 channels on the Netflix channel. Suggestions? Thank you.
P.S. I have confirmed the problem with Dolby, DTS, and DTS-HD
