Hi,
I have Sonos Beam gen. 2 with to Sonos One SL as rear speakers. As my wife is hard of hearing we use an apple airport express to connect her headphones to the Apple TV via AirPlay.
The beam is connected to a LG Oled via eARC. LG ist set to “passthrough”.
When we’re watching Dolby Atmos movies and activate AirPlay additionally the Sonos app shows “stereo PCM” and I hear at least up mixed stereo from the rear speaker.
But when I watch non-Atmos movies (for e.g. 5.1) the Sonos app shows Multi-Channel PCM 7.1 and the rear speakers don’t receive any sound information and are muted when we activate AirPlay additionally.
Can anyone help me to understand this behaviour? What can I do to at least have stereo up mix output on the rear speakers when watching 5.1 movies.
