I have a multi room system which has been playing up since the Sonos app was updated and I am still unable to fix the issue. I emailed the Sonos CEO months ago without a response and have tried hours in the phone to Sonos help without success. I’m pretty frustrated. 
I have a Sonance amp with six speakers wired into the sockets at the back of the amp. I use these speakers for my TV and music, all controlled through the app. My TV and amp are using the same WiFi. My TV is unable to link to the wired speakers so sound only plays out if my TV

rather than through the ceiling speakers. I’ve tried factory reset of the amp which doesn’t help. When trying to link TV to speakers via TV settings, the CEC isn’t working. Anyone know how to fix this? 

A Sonance Amp? Have you contacted Sonance? 

If it were a Sonos Amp, I’d have a better chance of guessing the issue, but I’m not at all familiar with Sonance products. 

At the least, I’d try a power cycle of the TV set, then make sure there weren’t any updates for the TV, and then flip off CEC and then turn it back on. It might be that the TV’s settings were reset by an update. I’d probably also try removing the connecting HDMI cable at both ends, the reinsert it. Normally, I’d suggest using the cable provided by Sonos, but I have no clue what cable is provided by Sonance. 

If it were a Sonos Amp, I’d also suggest a factory reset as a bad choice, it usually just erases any information stored on the device that Sonos would use to help you. Again, I have no idea what a factory reset does on a Sonance Amp.


Thank you Bruce. I have factory reset the amp a number of times without fixing the problem and the Sonos help desk have had me do this too. I need to try the CEC settings again but I think I did this a few months ago the ago without joy. I’ll have another go. 
If you have any other brainwaves in the meantime, please let me know. It’s ridiculous as I work full time and the Sonos helpdesk is only open on weekdays and I dont have hours to spend on the phone sorting out. Sonos have really let me down with this. I wish I hadn’t bought the products now. 


Thank you both. This is helpful.
