Forgive my questions if they seem silly but I am a newbie to Sonos! I’ve ensured the sound setting on my LG is set to ‘Dolby Digital’ and have a Beam (nothing else as yet). On my Sonos app it always says Stereo 2.0 even though I’m currently watching a Blu Ray with Dolby sound. Is this because I don’t have any surround speakers as yet? Will it only flip over to say Dolby when I have the surrounds in place? I assumed that it didn’t say that previously because I was just watching TV but now I’ve set up my Blu Ray player, it’s still saying Stereo.
