You may also want to try and setup the TV audio again. You can go to More -> Settings -> Room Settings -> Your Beam room -> TV Setup.

Have you attempted to unplug the power from the TV, wait a minute, and then plug it back in? I don't mean turning off the TV with the remote, I mean actually unplugging it from the wall.
I have a similar problem. Beam will not play tv sound which comes from a Humax Freesat box. It will play Netflix, Youtube, internet etc sound but reverts to tv speakers for tv.
I am having the same issue. woke up this morning and Beam would not play tv audio but would play music.
Try unplugging your TV from the wall for two minutes, then plug it back in. After plugging it back in, wait a minute, then test.
It might be worth double checking to see if there’s a software update for the TV, as well.
Hey there,
had the same issue but managed to sort it out.
Tv is an older Samsung Smart (UE46ES8000).
After a number of attempts with the App saying all was well - bit still no sound; i tried fiddling with Samsung Audio options.
First weird thing, once the Beam was physically connected, most of the Samsung Audio menu gets disabled. Only way to get options back, was pull the ARC and disconnect/restart the tv.
Once back on, with Samsung menus restored, switched the tv to internal speaker only, then Reset the audio settings for good measure.
This done, went through the Sonos App Tv Setup again, reconnected ARC and voila!, suddenly started working.
