Hi there @johnt74, If you have other questions about your Sonos products, feel free to reach out. Sorry to hear about this issue on your Sonos Arc and Samsung TV. What is the Model of your Samsung TV? Are there any pending firmware updates on the TV that you can install? It would also help if I’ll ask you to submit a diagnostic report for us to investigate further what could be causing this issue. You may reply to the thread with the confirmation number to assist you with this issue. 

Let us know how it goes and we're here to answer any further questions you have.
 

Hi Simon,

The model number of my TV is QN75LS03TAFXZA. I spoke to someone at sonos a few weeks ago that knows about this issue and I was told it’s on Samsung. My TV is up to date version 1403. The remedy is to unplug the arc wait 10 seconds and plug back in. Again I know this has been an issue in the past just have to figure out what needs to be returned the Arc or the TV.

Thanks for any help

Same thing started happening yesterday on my samsung tv QN65Q80TAFZA. Sonos was just installed a few weeks ago. Changed from wireless to hard wired with no improvements. The unplug tricked work for temp solution. Will be returning if it keeps happening.

The most frustrating part is the blame game between the two companies. Sonos at least acknowledges the problem, samsung claim it is not an issue that has come up!
