On JBL forums there are quite some discussions on this popping sound. In my experience the popping sound appears when there is some problem with the signs strength be it over Bluetooth or Wifi. So check that Bluetooth is switched on the speaker and check the signal quality at the JBL location. 

@Kevin_Z having the same problem here jbl link 10 crackling sounds, more severe when setup in group play, together with my Harman Kardon citation 300, Google Nest hub and Google mini. Only the jbl has this problem.

Playing as Stan alone speaker has less crackling sounds.

Changing my group to only the citation nest hub and mini, no disturbance what so ever. Jbl and nest hub are on the same desk in the same room.

@Kevin_Z further more I tested using different music apps as Spotify and pulsar+ chromecasting my group of speakers. On Spotify only the jbl has the crackling interference, on pulsar+ however jbl and nest hub have the same problem.

The problem is in casting to multiple cast devices when setup in a group. Deco M9 has a problem with that.

Something that should be easily fixed for a company like tp link.

Expecting a solution on short term!

 

Note. To clarify your suggestion of setting up the speaker in a shorter range to the deco nodes, I put my jbl link 10 in a range of about a cm or 2 right next to my deco node, crackling persisted!

I have the same problem with JBL link 20 and Deco M9. Tried all kinds of QOS/mesh settings to no avail. The only thing that cleared up the issue was removing the speaker from the cast group that also includes home mini and nest display. I don't use the group much so this is acceptable for now. JBL system firmware 1525. cast firmware 1.36.152.524. TP-Link, JBL and Google would have to get together to sort this one out. Chances are slim IMHO.

@axs hi, tried some more settings, it's not the speaker(s) played Spotify thru my surround receiver and connected speaker set which in turn is connected by a media player(box) with Spotify on it. Now I can play Spotify even on the speaker set connected to the surround receiver it shows as tvbox. But even here the crackling sound takes place.

Playing for a couple of minutes and the crackling sounds disappear.

So the problem is in the way the data is being streamed from the nodes to the speakers. As I understand it's a multi way data stream setup in a triangle and somewhere in those data streams the problem sits.

Tried several setups qos on/off, telephone which is streaming the data set as priority etc etc. It's clear to me the problem can only be in the data streams.

@MarcMommers 

Have the same issue as all above - popping and other disturbing noises when connected to M9 system BUT when changeing to connect to TV router/AP which is a Netgear the popping stopped, even when having the two JBL Link 20 grouped.

Sooo it must be a Tp-link problem!

I tried, as others, many different settings before tried this, connecting to Netgear instead, without any luck

I have the exact same problem with multiple JBL Link 300 and one JBL Link 20 speaker using a TP-Link Archer C1200 v2.0 on the latest firmware...

TP-Link needs to fix this...
