My Setup:
Plex Media Server + Nvidia Shield + TV(not eARC compatiable) + Arcana + Sonos ARC
Previously this setup was playing my 4k Atmos TRUEHD content no issues. But recently it stopped playing it all together. Will only play content if I switch the audio stream to AC3.
I read this thread below and it seemed to be pointing to an issue with the latest 13.x Sonos firmware causing the issue. So I updated my Arcana firmware to .84 but it doesn't seemed to have fixed the issue? Am I missing anything in terms of Arcana settings to get this working?
