I have the arc and 2 x ones and they work fine together for movies giving me both atmos and surround from movies on my Apple TV + LG tv.
But… I also have a blu-ray with music in 5.1 format. Can I somehow rip this and convert to something that can be played back correctly on my system?
For my dvd and Blu-ray collection I have ripped these and store them on a NAS which the Apple TV can access and I then play back using Infuse. Works like a charm. My music collection is also on the NAS and I can get the Sonos app to play back tracks from it.
What format should I pick for the music? Can the Sonos app somehow access and play it back in multichannel?
