Arc TV sound cuts in and out.

Hi Bruce, I suspect the same but how do you/I actually know whether there is a dodgy batch of HDMI cables getting around?

I guess we don’t. How do we know it’s not a dodgy issue with your TV? Or the power your home is supplied by your power company? Or a software issue? Or sunspots?

Feel free to spend the extra money on new HDMI cables, but if it were me, I’d be sure that there’s a money back guaranty if it doesn’t change anything.

And unless that cable is forty feet or more, it’s overpriced. 

I couldn’t agree more Bruce, thanks for the advice and time though 👍🏻

I’m having the same issue, started about a week back, now happens every day at least once per day.  Seems this is happening across alot of the products including ARC, Beam etc.  If I get told to reset it or chaceck my cables, this will be going back INSTANTLY.  Sonos needs to recognize this is a problem and give an ETA of a fix or I’ll just send it back and cancel my other product orders that are backordered.

Hi. I experienced the same issue yesterday. It was like the Arc had frozen. TV audio kicked in. The white light on the Arc flashed quickly for over a minute and then the Arc kicked back in. 
 

Mine is connected to a 2020 model Sony A85.

Same issue with my tv and ARC. tried unplugging (power and HDMI). 
 

here is the diagnostic: 1904797134

Hi everyone, sorry for the late reply.

@jlindstrom, the diagnostic is showing that the Sonos App isn’t connected to the Sonos system.

I would like to know the Network setup you have. I’ll need the model of your router. If you have other network devices like wifi extenders, Mesh systems, and the like, I like to know the model of those devices as well.

@Jbrow, the diagnostic only shows 5 minutes worth of data, I would like you to take a diagnostic when the audio cuts out and reply with the confirmation number.

@jste, the diagnostic shows 20 minutes of data, unfortunately, it’s after a reboot. I would like you to also take a diagnostic when the audio cut out. Can you also please provide the model of the TV.

@khaz22 and @StueyB, can you please clarify the model of your TV and take a diagnostic when the audio cut.

I would also like for everyone to check if there are firmware updates for your TV. 

Please reply with the model of your TV also take a diagnostic when the audio cuts out on the Sonos Arc before rebooting the soundbar.

I will try to assist everyone here. 

If you have other concerns, feel free to reach out.

Same Issue, have an LG CX tv and just sent diagnostics, conf #838225063

Also when watching Formula1 on Netflix the dialogue will switch from the arc to the surrounds (2 one SL’s) randomly, haven’t confirmed if it does this with other shows yet just noticed this problem now. And its not like the people moved behind you or something seems unintentional as it only last a few seconds then switches back to coming from arc, seems like a possibly related issue? 

Hi @mathenautical, thank you for reaching out.

I checked the diagnostic, the Arc has been rebooted 12mins ago in the diagnostic.

I would like to know if you rebooted the Arc? If so, I would like you to take a diagnostic when it happens and without rebooting the Arc.

This so that the diagnostic will have the data of it cutting out.

Please monitor the Arc and update us with your findings.

Hi guys. I’m having the same problem here. Just picked up my arc 2 days ago. I have a Sony x9500g TV. Have had 3 instances. Arc sound intermittent, arc losing sound sync, and sound stopping completely. Never happens at commencement, always 10 or 20 minutes.
