Don’t Factory Reset the SONOS.
With respect to the TV are you actually removing power when you turn it OFF, or are you using its tempt to put the TV into standby?
Is BEAM wired to the network?
With respect to power. Are all components (TV and Beam) plugged into the same power strip?
Thanks for the reply’s
the tv is wall mounted with both the tv and Beam plugged into a wall mounted power point behind I’ve left both plugged in but turned the socket off at each when trying to reset?
the beam is hard wired to the network with cat6 cabling.
its been working fine for the last 3 years until 2 days ago?
OK…is the power point you speak of some type of smart switch wherein turning on the TV triggers power to it and the Beam? If so therein lies your problem. Please post a response.
Hi there
no it’s just a regular PowerPoint, the whole setup has been working fine. It’s as if an auto update on either the tv or sonos has a glitch in it?
it shows up in the app as being connected to the tv, makes the chime through the speaker that it’s connected but then still no sound from anything being played from the tv.
might try and switch over the hdmi to ruel that out but that means getting the tv off the wall

The issue described and the timing of it is exactly the same as what I’m experiencing with my Sono Amp and the tv audio connection through the Amp.
Is this due to recent updates?
Yes! and I also tried reset everything, deleted the app to clear all data, and set up the amp like it’s brand new. And the issue still persists that the audio would only work temporarily and would stop coming through again.
Right now I just can’t use the amp at all cuz I can’t be resetting and unplugging replugging multiple times per day just for it to work temporarily. Extremely frustrating and you are not alone. Hoping there will be a solution soon.
It is so annoying, glad in a way I’m not alone with this because I was beginning to think I was losing my mind.
updated the tv software and it worked straight away but then when I turn off the tv it reverted to not working normally.
I might have to contact Sonos directly or Samsung to raise the issue?
Hi @Dank77
Welcome to the Sonos Community!
Reports are that a recent Samsung software update to multiple models has introduced an issue whereby Dolby Digital + (and in some cases Dolby Digital too) won’t play on external audio devices.
Some users report that they are able to get TV audio again by restricting the TV to play Dolby Digital or PCM audio formats.
I recommend you contact Samsung support for assistance.
I hope this helps.
Thanks Corry
I ended up speaking to Sonos who told me the same thing….updated tv software update and adjusted expert sound settings with Beam disconnected and ( touch wood) seems to have resolved the problem.
appreciate everyone’s help and advice with this
