Audio suddenly dropping out intermittently

​@DannyUFCfan 

Interesting. It’s been a long time so I”m not holding my breath.

I’m trying Wireless Audio Sync anyway and will report back any findings...

Me too lol

working, so far (early days) *touches wood again*

​@Rhonny I don’t know how you got on with your testing. I’ve watched a couple of hours of Apple tv dolby atoms and  Wireless Audio Sync might have fixed the problem! Now, I’m far from convinced that its fixed, but so far, so good!

Let’s be honest, it’s unlikely that apple or sonos will fix this, so if anyone find this in the future. Try out this fix. 

The announced real passthrough mode with TvOS 26 may show some effect here.
Lets wait it will really show up and what Apple understands by real passthrough ;-)

Good point. I forgot that was coming.

Today’s update is that, the problem has returned like a bad smell lol 

Ok, time to put apple tv in stereo mode and be done with it until it’s fixed 

I thought it was worth updating this thread. Issue is with any 5.1 mix on Apple tv. I’ve set apple tv output to stereo and the issue has 100% gone away. It sucks I’ve had to do this but whatever.

Let’s hope the TVos 26 update later this year either fixes it or allows a workaround. 

Anyone tested to see if the new Apple TV OS has fixed this issue? I have not had a chance to test it yet.

Yes, unfortunately nothing changed.
I have been told in a Reddit thread the new feature was only an assumption by some guys analysing settings in the Beta. But no real announcement by Apple.

So all as before :-(

Can confirm myself that the problem still persists.

Oh well, I guess I’m watching anything via apple in stereo, then….

Either that, or buy a different soundbar and ditch sonos. 

Newbie here.

So I have this problem and I DON’T have Apple TV. Mine is a Samsung 75” TV connected with eARC.

I bought a new ARC Ultra, Sub 4 and Era 300s.

The system is set up via a Vigor Draytek router. I have tried wired and wifi. Same problem persists.

I have replaced the HDMI cables with expensive certified cables.

I have gone through the unplug everything, reset, add TV in the S2 app and more. Problem persists.

But there is more….

A day after we got the system, the problem showed up. I then went hunting around the forums and trying this and that. Eventually, I was convinced I had a faulty Arc Ultra. So I sent it back and had it replaced.. The problem persists on the new Arc Ultra!

So I tried my Sonos system using another TV, this time an LG TV. Problem persists!

Conclusion:

It looks like it is a Sonos problem. Two soundbars tried, two TV’s tried. But I read that some people have sorted this using an HDFury Arcana. I have one on order….bloody expensive….but if it sorts the problem out, I don’t care.

I will post an update once I receive it and try it.
