Hi we have multiple sonos products in our system.

Been using Sonos Amp for most part of the year. Several weeks ago it started having crackling sound while watching TV on all apps.

Sonos System still on S1. Sonos Amp wired thru ethernet and hooked to an LG C8 oled via hdmi arc and paired with a Sonos SUB v2.  Tried setting the sound output to both PCM and AUTO still the crackling remains.Happens every now and then but now getting more frequently. Sounds ok when I switch back to TV audio output using the built in speakers but when i switch back to the AMP via hdmi arc the crackling resumes. Playing music thru sonos using spotify and tidal no issues. All firmware both on TV and SONOS are updated.

Will updating to SONOS S2 solve this? but i really do not want to update as I have a mix of new and legacy devices.

I know the crackling issue here on the forums are a plenty but been a SONOS user for almost a decade and this is our first time with this issue. Yeah its been a frustrating experience at times but when it works its golden.

Please HELP.

Thanks

 

 

 

Hi @mlabadan, Thank you for reaching out and welcome to the community. Sorry to know about what’s happening with your Sonos.

crackling happens on any app or any sources (shieldtv, appletv) connected to the tv with sound output over hdmi arc to sonos amp.

no crackling at all if i chamge back to tv speaker output.

issue happens over hdmi arc to sonos. changing hdmi cables also does not help. used a different set of powered speakers over hdmi arc with no issues.

no crackling also when streaming music.

interference? maybe so, if the amp is connected via wifi...
the sonos amp and all the source devices connected to the tv including the tv itself is wired via ethernet cable. crackle happens only on hdmi input of amp. no issues whatsoever streaming music via sonos app.

Hi @mlabadan, thanks for the update. About this concern.
