Hello - I hope someone can help me with an alternative for my Sonos setup.
System Overview:
I have a EA3 controller that works with with my Sony 5000ES receiver.  The system is in the basement away from my living room 5.1 setup.  Control4 manages the receiver, Sonos, Roku, Oppo, xBox and a DoorBird.  I gave up connecting Oppo, XBox and DoorBird after multiple attempts.  This might be a topic for another thread.  This was a new build about 2 years ago and the dealer did all wiring of house and involved from the beginning.
Sonos Overview:
Sonos has really been the major disappointment in my system and looking for help.
If I want to listen to Sonos on my main system in living room I use the following steps:
Turn on control4 and select Sonos. Start a Sonos favorite station. Then I go into my Sonos app and add the other Sonos zones to my main room so I can select other music options. I still have to control volume for main room from control4 as the dealer had the Sonos volume fixed  So it’s quite a process to get everything up and running, additionally controlling volume from two places on multiple zones is frustrating Potential Sonos Fix:
I’ve learned my Sony STR-ZA5000ES receiver has music connect option.  I could link my Sonos connect to receiver via optical and provide the MAC address.  This option sounds like i could break free from control4 and manage music everywhere via Sonos app.  My dealer said this wouldn’t work or cause issues in my system?  Looking for a second opinion?  I’m afraid to try it on my own as I could cause issues with control4 and receiver, requiring another service call.  I appreciate any advice.
