No sound between TV and ARC since app update

Disconnect everything from the TV and unplug the Arc and TV from power for a couple of minutes. Plug everything back in but keep everything disconnected. Make sure CEC is enabled in the TV settings. Run TV Setup in the Sonos app and follow the app instructions. When the app instructs you, connect the Arc to the TV’s HDMI ARC port using the Sonos-supplied HDMI cable. After the Arc has been successfully connected, connect any other devices to the TV.

I have the same issue with the playbar connected to the tv by spdif. The reply above did not solve the issue here.

The playbar also does not switch to tv source anymore, manual switchibg to tv does not help though.

Yup, I have the same issue with a Beam (Gen 2) connected to a Samsung TV (via ARC). This also occurred after the last update (the one that changed the visual look of the Sonos app). I’m annoyed I can’t change the volume, turn the TV on or off, change input, etc. 

Why do I have to factory reset my whole Sonos setup (a Beam, Sub, and 2 Play:3s) at least once a year due to an issue like this after an update? I’m definitely done with these products - once one breaks, I’m upgrading to something reliable.

This latest download from Sonos is so beyond acceptable. I can no longer connect my iTunes library or my television to listen too. I spent thousands of dollars for them to do this. They seem to have decided after taking money from us for years to change their platform. I have went through various changes and always seemed to make it work. This time they have basically disabled my ability to use the system. I WILL NEVER BY ANOTHER SONOS PRODUCT AGAIN!

Same problem, unable to get sound from the TV through the Play bar, subs and Sonos speakers.

Sonos please fix ASAP

Same problem, working on this for 2 hours.  The benefit of Sonos used to be convenience.  Now that’s furthest from the truth.  I have a bunch of expensive paperweights.

I’m a Sonos dealer. We’ve been fielding calls for the last 10 days dealing with this crap!! My home system just ran the hardware update, so long TV audio! 

Many people bought their product because they promoted the advantages of being able to use the sound system just like a theatre and now they have taken it away. They should be sued for doing this. My system is completely useless now! I have spent all this money for it to be screwed over like this is beyond frustrating!

Have the same issue with a playbay with spdif input with no sound - after the latest update here in may 2024.

Same. Just had the new app installed and spent an hour trying to get the sonos arc connected to my samsung Q80 tv. No luck. Why do they do this to us. Nothing on the problem solving sites. You would think they would have tested this. Music is fine, but not the tv connection.
