Sonos Arc loud pop then audio loss

Either way, I expect a fix from someone. But I just don’t see this as being a TV manufacturer problem. If it is, Sonos needs to work with them and find a solution. With that said, I don’t believe it’s on the TV manufacturers. That sounds like a cop out. 
 

I have a Sony A80J. Has anyone had issues with an LG or Samsung?

The only common denominators I’ve mainly come across is the ‘popping’ matter seems to be related to Dolby Atmos audio over LPCM, from either an Apple TV, or Xbox, but it’s also not just Sonos branded products that have the issue, I’ve seen it reported with other brands too, but people keep saying that was in the distant past, plus there’s always one or two exceptions to the rule (as always)  - but I can only mention the things I’ve read - I still think it’s a codec(s) issue. I have never had the issue here with my Arc or Beam(s), I don’t have an Xbox or Apple TV that supports Atmos over LPCM, so that’s also part of my own reasoning for suggesting these things.

We’ve had reports of both both LG and Samsung TVs being affected. The most interesting one was of an affected Samsung TV that had only ever used built-in apps, but which uses LPCM for Atmos. So that is a common denominator. Let’s also note that LPCM wasn’t supported at Arc launch, so all the reviews missed it. 
 

Sonos has suggested that other soundbars have the same problem. I don’t think that’s true. Problem reports of other soundbars might have used the word “pop”, but described different problems: a rhythmic clicking, static noise, etc. I’ve seen no systemic reports of our slamming pop followed by sound cutting out. 
 

In my assessment this is a Sonos-specific issue. Months ago I even worked with Sonos to submit recordings of the pop with the Arc in dev mode, which lets you download an internal log of what happened which I submitted to Sonos. Not only did I submit logs for Apple TV and Xbox producing the pop, I even submitted a pop where no audio was playing and the Apple TV was just on screensaver. 
 

Unfortunately since then Sonos has chosen radio silence. 

I’ve had the problem happen on both Sony and LG TVs in my exact same setup.  I swapped out TVs over a year ago

If they have the data there’s no valid excuse as to why they can’t fix it. You cannot sell an Atmos supported soundbar without actually supporting Atmos to its full extent. No where on the box or written materials was there “does not support certain Atmos capable devices”

They either fix the issue or offer refunds for the systems that have issues. It’s truly that simple  

Hi,

Just to add I have had an ARC since not longer after release. Xbox series X and pops from the start. Replaced one ARC kind of just waited for the firmware fix that hasn’t arrived,

Tried the CEC and atmos disable solutions. Neither of these worked, still get pops. They have suddenly become much more frequent.

I also note the Sonos ERA have the same issue. I am not sure why reviewers are not picking this up. I did email a couple to say they should be calling it out.

I am guessing it’s not fixable and Sonos are just staying quiet but they are at a point where they need to say not compatible with Xbox and Apple TV as a minimum.

Even if turning off atmos did work this is their atmos product. Its like a car manufacturer telling you to not go above 20.

I am going to be asking for a full refund on my Sonos setup and when they refuse I shall take them to small claims court (UK) as the product is not fit for purpose.

Suggest others follow suit.

It’s not a good look. As I’ve stated before I’m a home theater installer and have generally recommended Sonos over any system other than a receiver setup. That’s come to a complete stand still until Sonos fixes this issue as I cannot recommend something to a client that doesn’t work properly in my own home. That’s quite a bit of lost sales as I have sold quite a few of them. I am not sure Sonos cares but whatever. 
 

Be better. Don’t make Bose look superior to you…

Still not one single word from the Sonos rep ? @Corry P 

I have the problem since March 2022. And I tried all the things called here. All without success.

Finally I read that you should turn off trueplay and then run Dolby Atmos MAT. I wanted to try that next.

If you're experiencing a loud pop followed by audio loss on your Sonos Arc soundbar, it could be due to a few different factors. Here are some troubleshooting steps you can try:

1. Ensure the Sonos Arc is properly connected: Check that all cables are securely plugged into their respective ports, both on the soundbar and the TV or audio source.

2. Check the audio source: Verify that the audio source (TV, streaming device, etc.) is set to output audio to the Sonos Arc. Check the audio settings on your device and ensure it is correctly configured to send audio to the soundbar.

3. Restart the Sonos system: Power off the Sonos Arc and any other Sonos components you have, including the Sonos app. Wait a few seconds, then power them back on. This can help resolve temporary software or connectivity issues.

4. Update Sonos software: Ensure that your Sonos system is running the latest software version. Open the Sonos app on your mobile device or computer, go to Settings, and check for any available updates.

5. Reset the Sonos Arc: If the issue persists, you can try performing a factory reset on the Sonos Arc. Keep in mind that this will erase any custom settings or configurations you have made on the soundbar.

6. Contact Sonos support: If none of the above steps resolve the issue, it's recommended to reach out to Sonos customer support for further assistance. They can provide specific troubleshooting guidance or determine if there may be a hardware issue with your Sonos Arc that needs to be addressed.

Remember to consult the Sonos user manual or support resources for detailed instructions specific to your model and setup.
