Sonos Arc loud pop then audio loss

Really starting to get frustrated by this problem, and based on the other users here it seems to be a little more widespread then just random individuals.  Would really appreciate a statement from Sonos on what they are doing for this problem

Reason why i say this is because i have experienced this issue a few times over the last couple of weeks and have submitted diagnostics for each of them

Most recent ones are: 1118141455 and 1729108796

Each time i call in the only suggestions that i get are things like power cycling and software reset….none of these obviously have solved the problem

For a high end audio product, i would expect a little more than silence on the support side

Rant over

I’ve had the same problem when using my Series X outputting Dolby Atmos to the Arc. Really loud pop which did sound like a gun shot. This was a couple of months ago. I read somewhere to disable Atmos from the Series X and Ive had no problems since, however sort of defeats the object of having an Atmos soundbar. Was just having a look around the net today to see if the problem has been acknowledged by Sonos or has been fixed. 

I am having the same issues, Sony TV and Xbox Series X connected to the eARC port on the TV.  While using the Xbox I get a loud pop, like a gunshot, from the Arc and no sound.  I have to change sound source to TV and then back to the Arc to get sound back.  So far this only happens when using the Xbox.  I have been able to watch cable and stream from the TV with no issues.

Following on from my last post- it just happened again playing Dolby Atmos from the Disney+ app on a 4K Apple TV.

Submitted a diagnostic - 1763217727

Haven’t spoken to anyone in support as it's out of hours but I’ll try to get hold of someone next week.

I experienced this same issue last night.

Loud “POP” and sudden loss of sound from Arc. Sub and rear speakers functioned normally. 

After unplugging the power, and replugging, the Arc function normally again.

Was watching Netflix on the Xbox Series X with Dolby Atmos. Arc + Sub + SR + SL.

Diagnostic reference number #67513007.

This seems to be a disturbingly common problem with this configuration.

This happened to me Friday while watching The morning show on Apple TV 4K.

If it happens again will do a diagnostic and ring them.

Happened to me for the first time, less than 24 hrs ago. It has since happened 2 more times; both times during the movie Jungle Cruise. My setup is Arc + 2 Sub Gen 3s + 2 One SLs. I've had the full system with One Sub since December 2020 and never experienced this; added the 2nd Sub less than a week ago. Not sure if there is a relationship there.

Since this issue has been reported almost a year ago by others without some answer from Sonos, is very troubling.

I can't recall if the first instance was while streaming from my AppleTV 4K...but for sure the 2nd snd 3rd times were.

And that’s twice in two days for me, two different films on Disney+ on Apple TV 4K. 

After the first yesterday (and a power cycle) everything worked fine for about 3 hours of film watching (in Atmos).
 

Today I got the pop and loss of sound exactly 10 minutes into viewing.

Diagnostic is 968159060 for whatever that is worth.

This (and the seeming lack of response) is so poor for equipment of this spec and value.

Same issue for me as described above. My diagnostic report is 591027322. Happened with an Apple TV 4K connected to a Sony x900h while watching a movie with Dolby Atmos.

Apple TV 4K seems to be a common denominator for a lot of the reports.

UPDATE: I had an HD Fury Arcana which I used with my older TV that only had an ARC port (never had this issue then). I have not used it since getting a new TV with an eARC port. I decided to try the HD Fury and have not encountered the issue in the last 48 hours. For clarity the below is the setup:

Apple TV 4K → HD Fury → Video to TV eARC and Audio to Sonos Arc system

If this resolves the issue, it would not be ideal for most since the HD Fury is a 249USD device.
