I have an LG OLED55BXPTA TV connected to a Sonos Beam2 and S1 surrounds via HDMI eArc. There is a major difference in sound when switching between local channels. I have to increase or decrease volume massively to listen effectively.
I have searched online and fiddled with the LG TV Sound settings without success - currently DTV Audio Setting is set to Auto and Digital Sound Out set to Pass Through.
If I go into the Sonos App - About My System I notice that the if the TV is on the channel that is very loud then Audio In: is Dolby Digital 2.0, whilst most other channels have PCM 2.0.
In another room I also have a Sony OLED TV with a Sony ARC and it shows Audio In: is Dolby Digital 2.0 Plus on all channels.
How can I get Audio In: to be Dolby Digital 2.0 Plus on all channels from the LG TV? Any way to fix the sound difference?
