Newbie to Sonos.  Before connecting my new Sonos system to the TV  I have set up the ARC soundbar, connected two One SL speakers as surround and the mini sub.  They are operating as one unit playing music for now. I plan on connect the system to my Samsung OLED tv.  I also utilize a Fire TV Cube that manages the entire setup.  My question’s this.  The Sonos soundbar will be connected to the tv via EARC.  Typically, the Fire TV Cube has an extensive setup procedure to manage all devices.  Is there anything else I have to do on the Sonos side to ensure a successful connection before I run the Fire TV Cube setup?

Hey @buffaloguy,

Welcome to the Sonos Community and thank you for the question.

As long as you use the eArc connection, it’s pretty much plug and play with Sonos. Your Arc is just at the receiving end of the audio stream that comes from the TV. There might be tweaks to get the optimum sound quality delivered through the connection on the TV or the cube though. Perhaps other users have more insight for this.

Something you might want to consider though is Trueplay to tune your home theater set-up specifically for TV sound. You can find out more here: https://support.sonos.com/article/tune-your-sonos-speakers-with-trueplay

Hope that helps and you will enjoy your home cinema experience with Sonos!


As long as you choose to use the TV as the volume control and not the Arc, you should be all set using the Fire TV Cube to control everything else.  At that point, the TV’s CEC is in charge of everything, and it should work just as it did without the Arc as the audio device. 


Thanks.  I will post back next week when I set everything up.


I use a Firestic which works the same as the Cube.

Plug both in to theTV and things should just work.
