Sonos Surround Speakers crackle/static sound

I spent all last night connecting the speaker in different ways to the router directly and through the bridge with no success ie same crackling. This morning i tried again with a direct wireless and then a wired connection to the router to see if the line in would react any more positively. Connected an iPhone and at first i had the same crackling and then a low emitting hiss from the speaker when connecting the line in. Rebooting the speaker removed the hiss which came back as soon as music was played no matter the network connection type.
I read another post about an issue with the switched mode power supply perhaps causing the hissing noise. The speaker which is causing the problem has not been used regularly and left switched off for long periods. I decided then to reboot once more which removed the hiss and crackling and leave the speaker switched on for some time in standby to see if the PS would perhaps settle down (i appreciate this does not sound too technical). Result is that I came back later in the day and the speaker is playing perfectly in all rooms which i have moved it to. No hiss, no crackling No changes to the network or the settings, just factory resets on the speaker, reconnected to the router and left it switched on for a couple of hours.
I did ask Sonos earlier today if the Power supply could have been the source of both crackling and hissing with submitted diagnostics but have not had a reply yet.
I have to also add a comment to p123 above. The speaker I had the problem with is a single unit in a second home and as i said not used too often over the last 2-3 years. In my main home I have a play bar, play 1's a sub in the living room, play 5's and a sub in a family room and a connect amp, deck and JBL speakers in a lounge with a Boost also in place. I have used Sonos for years never had a problem with that set up and cannot fault their product in any way up to the point i had the above noted problem with the gen 1 play 5.

Hi there, I bought my Sonos Playbar yesterday and I also orderd 2 x Sonos Play 1 and they will be arriving tomorrow. I have the same Problem with "crackle/static sound" like everbody is discribing. I am very dissaponted about it because i was looking forward to enjoing the surround system but now when i turn off the music or Tv i still hear high pitch noise and it is really annoying. I can even turn off the sound system. I have to plug it off.
I have tried everthing to solve this Problem like:
- connect Playbar only with WLAN
- connect Playbar only with LAN
- change the Plug from the other systems like TV, Playstation, router
- I also put the Playbar far away from the TV

and now I have submitted the diagnostics for you guys to solve the Problem My Number is 8135499
Can you please check

Thanks

Hi there!

I recently purchased a PLAY1 in the US while on holiday but I live in Canada... returning it might be a bit of a stretch. I am also experiencing these static/crackle sounds - diagnostic code: 8305783. We already had a PLAY1 and wanted to add a second room because we were, and ARE quite pleased with the sound quality of these little guys. The first one hasn't had any issues and we've owned it for a year. The second unit had this issue right out of the box.

Hello there, lloydhebert. Thanks for posting your diagnostic report and welcome to the Community, Do you hear this pop on all speakers or is it on a specific player? Are you able to reliably replicate the problem? If so, please tell me the steps you go through to make the pop happen again.

Thanks!

Hello everyone. Thanks for the diagnostic reports. Can you let us know what is the make and model of the TV you have connected to the PLAYBAR? This will help us to take a closer look at the signal being passed along. Thanks in advance!

Thanks! It’s a Samsung UN49KU7000FXZA. The issue seems to be isolated to streaming video (not a problem for cable -yet).

Hi there, WizardOfFoz. Thanks for the diagnostic report. It seems your Kitchen and Conservatory players are having a hard time maintaining a wireless connection to your Huawei router. Specifically, the Kitchen player is dropping up to 25% of the data due to interference. Check out this helpful FAQ about reducing wireless interference and let me know if you find it helpful.

If you continue to run into problems, I would recommend giving our support technicians a call to troubleshoot in real time.

Thanks for the diagnostic report, ljsommer. I was unable to pull up any information from the report. This normally points to a problem getting data to or from Sonos on the network. Could you tell us a little more about the local network? Specifically, I am curious about the make and model of your router and if any of your Sonos devices are plugged directly into the main routing unit. If there aren't any please plug any of your Sonos devices into the network and submit another diagnostic report. I'll be happy to see if we can get any data from another report.

Thanks in advance!

I’m having the same issue with my playbar and sonos 1. Heres diagnostic number 2105245159.

I am having similar issues with my play1 surrounds.  Reset, unplugged/replugged, true tuned - have done it all and there is a still a loud static hum.  I ran a diagnostic and the number is 1228036646.

Hello, I found this thread because of a similar issue. I have a player, two play 1 as surround and a sub. Just recently annoying static is coming from the surround play 1's. Usually during watching broadcast television. Its really annoying. I'd appreciate any assistance. Diagnostic # 11776399993. Thank you

I'm having the issue with my Play 1 speaker crackling. It's not consistent, but seems to happen when background sounds/music increase in volume while watching movies.
