The Arc plugs in to the eARC output from your LG, and will play anything playing on the screen of the TV.

The Move can’t be used as a surround speaker. It has to be set up as a separate “room” in the Sonos software. You could “group” that “room” with the Arc, but there would be a slight delay of the TV’s input on the Move, although they would be in sync if you were streaming music. 

Bruce, 

Thanks so much for your quick response. The Arc will be connected to a differentTV than the Move. I think that may prevent me from watching the second TV with the Move, and hearing the audio through the Arc. The first TV with the Arc may be off or watching a different program. 

Might there be another solution??

The Move really isn’t designed for home theater use, although I suppose you could potentially connect it using the Move’s Bluetooth feature. But I wouldn’t want to guaranty any sort of lipsync, not to mention if the TV has the correct Bluetooth codec….and it would be only receiving a stereo signal across bluetooth. It’s just not designed for that type of use. Sonos sells the Arc and the Beam as home theater speakers.

But if they’re set up as two different “rooms” in the Sonos app, there’s no reason why they couldn’t both be playing at the same time. 

Edit: using two different input signals, the Arc via ARC or eARC, and the Move via (hopefully) Bluetooth.

Bruce,

You are spot on! I used the Roku app on my phone to control my Roku Ultra. I clicked on the optioin to listen to the show on my phone. Connected my phone via bluetooth to the Move. It worked well however there was a delay in the audio. So there is a delay between the picture and the audio. 

I truly appreciate your help. I have my answer and will use the Move as designed.
