Hi,
this has been doing my head in. My Sonos app only shows Dolby digital 5.1 for ps5 game audio.
I have set the tv to pass through, changed ps5 audio to av receiver and 7.1 ch and have changed the audio priority to dts or Dolby.
I have a Samsung q80t and it apparently can’t do lpcm over earc. I should still be able to do Dolby digital plus 7.1, no? Others have confirmed they get 7.1 audio with this set up so it is possible.
