I’ve been having a pretty frustrating time trying to set up my Sonos system these past few weeks. It works for a bit and then things seem to disconnect and I end up having to reset everything and go through the entire drawn out setup process again and again. I have a Sonos Arc Sl, a pair of 100’s and a sub Gen 2. I know the arc set up isn’t designed for projectors but when it works it’s amazing. My projector has a eARC port but for whatever reason my Sonos arc won’t recognize it and fails to output Dolby Atmos. After buying a new highspeed hdmi cable and trying other things to fix the issue I decided to just bit the bullet and buy an HD Fury Arcana to resolve it. After installing the Arcana the everything was working for a few days, I was able to get Dolby Atmos and Dolby Vision and my Apple TV remote was able to control volume of the arc. Yesterday the system decided stop letting my Siri Remote control volume of the system. I tried messing around with a few setting and some quick resets of Apple TV and remote and other suggestions I found online but nothing seemed to help. In the Sonos app when I try the tv setup option the app will not recognize that the system is connected to the eARC port and will just freeze until I kill the app. I then did a full reset of the entire system hoping that would solve the issues but nothing has changed. I’m still getting Dolby vision and Dolby Atmos but the Siri Remote won’t change the systems volume and the app still freezes when I try the tv setup option. Any help would be awesome because I feel like I’ve tried everything and looked into every Reddit page and forum I could find 

Try this:

Disconnect the Apple TV and projector from the Arcana.

Unplug the Arcana and projector from power for about a minute.

Plug the Arcana and projector back in but keep everything disconnected.

Run TV setup in the Sonos app. Follow the app instructions.

When the Arc has been successfully connected, connect the Apple TV to the Arcana.


You are amazing, that instantly worked!! Thank you so much, you have no idea how much of a head ache you just saved me!
