The fact that everything works as expected in DD, DTS (no +) mode, tells me its a Roku software implementation issue. Oh well, maybe next update.
It looks like 8.2 was pushed out on my Hitachi Roku TV on 10/24. Since then I'm having issues with buffering on Pluto TV, multiple channels. Sound getting out of sync on Roku app. Reuters TV app, main news screen will turn white, audio (internal speakers) plays fine. The main video stays white, unless I use the down arrow and activate the top banner. Pausing play back will return a full video picture, pressing play and it goes white again after a few seconds. While all this is occurring, the bottom banner stays active and updates with the current story so it's not a total loss of video signal, just the HD portion.
I have a Roku Ultra on another TV, running Rev 8.1, without any of the problems. I connected the ultra to a HDMI on the Hitachi and it works fine so it's not a wireless issue, it looks directly related to the 8.2 rollout.
I've tried hard shutdown, unplug the TV for 5 min - No change
Delete and reinstall Reuters App - No change
Any ideas? You guys have a memory issue with this version? 8.2.0 Build 4165
