Hi @ZiggaZig, thanks for reaching out and for submitting a diagnostic report of your Sonos system, upon checking, the HDMI Arc status is disabled, Kindly check on your TV settings and enable the CEC and check if that will work.

Hi there. 

Thanks for the update. Unfortunately it is still not working, I have checked the settings on my Samsung TV and ARC is active. I tried troubleshooting the HDMI  cables in my TV and it does not register anything plugged into ARC. I also tried another HDMI cable and same thing. I just ran another diagnostic, 1587622569.

Could it be the ARC port in the TV is faulyy? My TV is approximately 4 months old.

Should I try an optical cable?

Thanks.

Hi @ZiggaZig 

In addition to the trouble shooting you’ve done thus far I’d contact Samsung technical support they may have an answer.

Hi there. 

I worked it out, I needed to reset HDMI on the tv by unplugging all cables and switching power off for 10 minuets, then setting up again. Works perfectly now.

Thanks for your help.

Hi @ZiggaZig, thanks for the update and for sending the diagnostic report. I’m glad that it worked after the unplugging and replugging of the cables. If there is anything else I can do for you, please, don’t hesitate to let us know.

And does it keep working?  I have to do this procedure almost every day in order to have TV-sound through my beam.  I was hoping for a more permanent solution (I also have a samsung TV).  Is this a known problem with samsung or also with other TV-brands?
