Hi using the above TV with a BT TV Pro box connected Audio set as below
HDMI-eARC mode Auto
Digital Output Audio Format Passthrough
Dolby Atmos On
When playing movies or programs from BT TV box in 5.1 all is fine
Playing from Netflix or Rakuten all is fine
Playing DVD via HDMI all is fine except when playing a DTS soundtrack when on passthrough I have to select Auto and can only get 2.1 PCM ??
