Dolby Sounds option gone after update

by bruxo00

Hi, so, 3 days ago I had a problem with Plex and I found out that I could fix it by going to the audio settings, setting the Dolby Sounds to RF, setting Digital Audio Format to Manual and enabling every option. That way I could play my movies directly from Plex without transcoding. But, yesterday I updated my Android TV and now the Dolby Sounds option is gone! Now I can't play anything on Plex because of this. Even the movies that don't use DTS codec won't play anymore. I already tried a factory reset, and it didn't work. The option is simply gone. Is there a way to fix this? Or this box just became useless, since I only use it for Plex? Anyone with the same problem?

A TV? A box? Be more specific

I have seen this issue too, in my case anything with DTS sound would not play. When i changed the audio output to SPDIF things started working. Not sure if its Mi Box S issue or plex as i had updated plex too around the same time. HDMI output is still being passed correctly.
