Our sonos playbar all of a sudden stopped playing the TV sound. Still can played over but not TV sound nor DVD nor Apple TV. Please help.

Oh, my problem is now solved. It decided to play after i try playing youtube.

Glad to hear it's working for you.

I have had my Sonos product for over a year and everything worked great. For some reason now I cannot hear sound from my Samsung Smart TV (UN65JU7100) through the Sound bar and my two play 1 speakers. I can play music (E.g. Pandora) from my phone and sound comes from all the speakers. I unplugged the soundbar and it did not make a difference. The optical cable attached to the Samsung one connect mini to the Soundbar has a Red light. I even tried using a high end optical cable (new) and it didn't change anything. The TV plays audio from the TV speakers but when I change it to audio out/optical to hear the TV sound through the sound bar nothing happens. Diagnostics # 7593421. Please advise what I need to do.

Diagnostic # 7671146. New LG C7 TV - the sound stops randomly when I watch TV. It has not dropped yet while playing Xbox. Please help, this is ridiculous.

Have you resolved this issue? My tv and Sonos system has done the same thing after a Sonos firmware update. I had to change my tv setting to PCM instead of Dolby Digital and I now have sound but unfortunately only in Stereo. I no longer have Dolby Digital 5.1 when I watch tv (Cable, Netflix, Blu-Ray). I hope a fix will be coming out soon because this is annoying...

Exactly same problem here, after update to 7.4 this happens. Some tv channels plays fine, but some won't. Have problems with my Apple TV too. If I set to pcm everything works. But want did 5.1, I guess there is something wrong with the update. Before everything worked fine

Same here (diagnostic no. 7753793). Both the sound from the tv optical and xbox one optical stopped working after the update. Changed the sound settings on the tv and xbox to PCM and stereo and the sound's back.

Come join the "fun" here if your SONOS system stopped working after the latest update...

Having the same issue and SONOS has no fix as of right now. I can't believe this!!!!

It's very upsetting to have invested all this money and now I can't enjoy my system, I have to switch to PCM and it sounds like crap!!!!
