New Beam Gen 2 and Sub Gen 3 owner -- my first Sonos speakers.

My Apple TV 4K is connected to my Samsung 6100 TV via HDMI. The Beam is connected from the TV via the dedicated ARC HDMI port. HDMI-CEC protocol (Anynet+) is turned on.

I’ve confirmed through the Sonos app that when watching TV I seem to only get Stereo PCM 2.0 output, when I believe I should be getting some kind of virtualized surround output. Am I missing something? Or misunderstanding?

@Alderking What exactly are you watching on the Apple TV 4K?

Under the audio settings on the Apple TV, set Change Format to ON and set the Audio Format to Dolby Digital 5.1.

Is this link your TV user manual?

If so, from a quick glance through, perhaps try setting the audio-out to Dolby Digital Plus and switch off the TV’s in-built speakers, as it mentions this information on page 97:

‘Some digital TV programmes provide 5.1-channel Dolby audio. This TV converts Dolby audio to stereo audio so that it can play the sound through the TV’s speakers’
