    Hi, I'm seeing the same problem with a setup of Pulse soundbar and two flexes, grouped into home cinema, all Ethernet cabled though, and different router (Cisco EPC 3925) I'm experiencing the static noise randomly during dolby digital playback.

    Hope someone has a fix to this?!

    I did a factory reset on all my Bluesound devices all at once. Now the whole system is just working great!

    Ok thanks for reply

    Did you also had problems, crackling or no sound from flex speakers, when using TV in combination with Surround grouping ?

    Richard, I also had the same problem with the crackling and the lack of audio on the flex. I hear some continuous noise. tonight I try to make the rest of the factory of all the speakers

    I reset all the speakers, the situation has improved but often the sound reproduced by the surround flex goes intermittently. Precise that all the speakers are connected in wifi, but the router is an Orbi and the signal is great ...

    Hi Marco,

    Have also reset all speakers but still have intermittently and crackling sound when using Home cinema group.

    The problem isn't when using only soundbar or stereo group with 2 flex.

    Flex on wifi by Cisco router and soundbar with UTP.

    Iam thinking about to return the whole system because there is still no solution apparently.

    Hi Richard, I think I've solved it. I contacted the help center and checked the speaker logs. They found that one of the flex surrounds had -61db of signal. This results in loss of audio information for both surrounds. I solved simply by approaching the Orbi router to the speaker that had difficulty. Try it too. You have to check the wifi signal via BluOS app on the single speaker (to do this you must first delete the fixed group). When it will be "excellent" (image of the wifi in blue) then you will no longer have problems. Otherwise you have to go to the ethernet also via powerline. Hello. Let me know how it goes.

    I am having similar issues with a new 2i system. Surround content works about 5% of the time, the rest of the time it unlistenable because of the static/dropout from the real Plex speakers. Stereo music played across the different speakers works pretty well, I rarely have issues with music. But TV, movies, and games, the playback in 5.1does not work even remotely reliably for me. My internet is good, my signal strength is good. The system seems unable to handle 5.1 playback reliably. I have a thread going with Bluesound about this.

    I have similar issue with a setup that consists of 

    - TV (optical audio output)
    - Pulse 2 (receives optical audio content from TV)
    - Pulse 2 mini (grouped with Pulse 2)

    The Pulse mini (~50% of time) would produce a lot of noise/ dropouts.

    From other users comment
    (especially the first comment from "Morten AN", stating that issue exists with "a setup of Pulse soundbar and two flexes, grouped into home cinema, all Ethernet cabled though"),
    I think the wifi connectivity is not likely the root cause of our issue.

    My guess is that the issue is originated from the "optical data distributor" (ie. the SoundBar, or the Pulse 2 in my case), due to the demanding tasks they have to handle simultaneously (ie. Receive optical data from TV, Play the Audio, and Transmit the optical data to the home ecosystem).
    [want BlueSound to confirm if this is true]

    Assuming the root-cause of our issue is the overly high workload on the SoundBar (or Pulse 2 in my case),
    I am guessing 2 solutions:

    1. Get a Node to do the heavy lifting of the optical content transmission.
      This way the SoundBar (or Pulse 2 in my case) does not have to do the transmission. (ie. focus on Receiving and Play sound)

    2. BlueSound needs to improve and make sure its own products can do perform the functions as advertised,
      or otherwise make restrictions to tell users what would work vs what wouldn't work.
      (ie. I want to be informed if merely a SoundBar is not sufficient to drive Home Theater with optical input source.)

    I hope someone from BlueSound can verify my "theory" and make comments. Thanks!

    Hi Nic

    You are close... what is being overworked is not your SOUNDBAR but your network router in a high amount of network interference. Check out some tips at www.bluesound.com/network101 and then select Help, Send Support Request and we can help troubleshoot your environment.

    Hi Tony,

    Next to the sound bar I have a set pulse flex and a set of pulse flex 2i.

    When optical output from the TV is send to the 4 plex speakers, all is fine.

    When old plex speakers form a stereo pair, the rumbling noise is not existing.

    However When the plex2i speakers form a stereo pair, the noise is extreme. 

    All speakers are connected via 1Gb LAN switch. When another source (not optical on sound bar) is chosen on the sound bar, all works fine with both the  stereo plex and stereo plex 2i.
