Hi. 

I have had a sonos beam for around 8 weeks now and it did work perfectly. 

The beam keeps intermittently connecting and disconnecting to the tv.

It is connected to the tv via an hdmi lead into the hdmi arc port in the tv. 

I have tried powering everything And reconnecting, i have tried 3 different hdmi leads (which all work on other products fine).

I have tried wireless headphones to ensure the tv sound works ok. 

Has anyone come across this issue before and could help? 

Thanks
