Audio suddenly dropping out intermittently

I did do the system diagnostics over chat and no issues were found. However, IIRC this was not done close to one of the drop outs.

Can now confirm that audio still drops on apple tv after changing HDMI port. I’m baffled by this as it was working perfect. Even unplugged the the switch 2 from hdmi.

The Apple TV box does have a known issue when watching content in Dolby Atmos that in some setups with soundbars (as it my household annoyingly), sound will drop for a second about every 20-30 mins of content.

There appears to be no fix on earth, so I just get on with it… It’s only with Apple TV box/Dolby Atmos content on soundbars it would appear. Not sure if it’s limited to Sonos soundbars or not. 

As previously suggested, don’t do ‘chat’, call in. 

Full disclosure — I’m not an Apple TV user.

I’ve poked around a bit and this seems to be an Apple TV issue — regardless of the playback system.

Really? Even if it was working perfectly ever since I got this set up?

Either way, I might be getting somewhere! Spoke to sonos via chat, this evening who told me that they ‘detected an interference with the connection of your speakers’. So, I’ll reboot my router, tomorrow.

I guess, if it comes to it and the issue is wi fi related, I could go wired? 

Why would the issue be WiFi related? You are using an HDMI connection for the Apple TV and other connected devices.

Well, they told me to reboot the router so they obviously think that could be the problem. You don’t think it’s wi fi related? whole system is connected via WiFi, no?
 

I’m going to try later, so we will find out then.

​@DannyUFCfan - you may like to try a reset of the Beam and you TV.
There are a lot of issues reported that are likely solved by this tasks.
This may like issued by replacing devices, or playing around with it when you changed your setup or just have a new one.
I had an issue with pumping sound I found reported by somebody else and the suggested solution was factory reset of the Arc. That worked for me.
Same time I had this sound drop outs as well. For the moment it seems to be solved ty the factory reset by the Arc as well.
Originally I found this sound drop out issue with suggesting a “soft” reset of the TV. Means pull power, disconnect all devices, connect power and all sources again.
That was not needed for me. Maybe because I decided when adding the Arc again to pair it with my TV directly, which may cause some specific reset of port/device.
In worst case you could try a factory reset of the TV. But keep in mind to save the screen settings.

Thanks. I’ll try a few more things and report back. I do have the option to have a wired ethernet connection instead of wifi, if people think that will help?

I had drop outs even Arc and Sub connected via cable. Just the ERAs wireless because don’t like the adapter.
But give it a try. I would try with the reset first.
