    Hi William

    Please select Help, Send Support Request so we may review your system log file for irregularities. We have made no changes on this front so very unlikely it is a software update.

    Hi. I have the same problem. Using two Pulse Flex connected to PC with optical input through one of them in stero pair configuration. Only the one not connected with cable make the noise and problem is occuring only when I pause. If I press play and mute the source they are both quiet.

    Hope you can help.

    Yup, noticed it too for the first time yesterday on one of my Pulse Minis and my Flex!

    I wouldn't call it "static noise", more like a very faint whistling sound, and only audible when the players are on standby mode. Playing music and stopping it makes the sound disappear, only to reappear when the players go back to sleep mode (after 15 minutes I think). Interestingly, only 2 out of my 3 Pulses do this, although they are all operating in identical conditions and not far from each other.

    I'll be contacting the Support Crew about this, to be honest not so much because the sound is a problem in itself (you really need to stand very very close to the unit to hear it) but more because I'm concerned this may indicate some kind of malfunction which could damage the players on the long run.

    Hi I experience the same problem With my 2 pluse flex 2i speakers. When in standby mode there is this some kind of whistling / hiss sound. Very annoying even from a distance. Did any one found a solution or cause for this?

    Hi everybody, exactly the same issue for me. The ‘static sound’ starts the moment they go into standby mode. This happens on my pulse 2 devices and pulse flex. The sound is quite anoying.
    Dear support, what is causing this and how can it be solved?
    Cheers, Daan

    Hi Daan and Willem, 

    Following my post above, I did contact the Support Crew but did not receive constructive feedback (the usual "unplug, wait for xx minutes, plug back in etc.", which unsurprisingly did not make the slightest difference). So for me the issue remains, but the static noise if very faint (I actually raised it more because I was worried it might indicate malfunction or long-term damage to the Player, rather than because the static is an issue in itself) so not something I have pursued further.

    Thanks Marc, good point. I didn’t think about the damage to the player. For us the reason is more the sound when sitting close to the speaker. Support desk gave me the same instructions but did - unsurprisingly - not help. The shop where I bought them added a trick (which did not help either): turn the power plug 180 degrees…. Or try a different power group they said. any other suggestions are very welcome. Switch off stand by is not what I want to do.
    Cheers

    Hi Daan 

    I have escalated your issue to our Support Crew to investigate further...

    Marc - it is unfortunate you did not continue to work with our Support Crew - we stand behind our product. Yes we do have to perform standard due diligence. It is unfortunate you have continued to live with this issue for almost a year now without pursuing it (according to your request history)... if it is a hardware issue, we may have problems with warranty paperwork now depending on your region. That being said, we strongly encourage you to re-open a request.

    Hi Tony, 

    Well, they say you need to pick your battles...

    I battled for the nearly two first years of ownership of my Bluesound system, with permanent instability, unreliability and drop-out issues, involving numerous exchanges with the Support Crew. Finally, my issues suddenly vanished with a firmware update somewhere late 2020 (must have been 3.10.xx or 3.12.xx, can't remember), and my system has been stable since then, in the sense that I can listen to music without having to reboot, "ungroup" and "regroup" Players etc. several times a day. 

    In comparison, the static noise on standby thing is a minor issue and simply not worth the hassle, to put it bluntly.

    And my Players are out of warranty anyway.

    Marc

    Hi Marc, the problem you are describing “"ungroup" and "regroup" Players etc. several times a day. still exists for me. Any suggestions there? I did several reboots - allowed updates, but still grouped players ungroup and players sometimes are not shown in the app….

    Hi Daan, 

    Well... it's a very long story and I would not be able to report what "the" solution was: I spent dozens of hours trying to understand what could be wrong with my system and trying to apply fixes, including numerous contacts with the Support Crew who was sometimes helpful, sometimes not so much. And in the end, as mentioned above, all my problems disappeared with a firmware update, in other words it was not me doing something on my end which fixed the problems but rather Bluesound changing something in their firmware (and I will never know what) which did the trick. 

    Among the things I did during the whole process, I can perhaps mention installing a mesh network (Netgear Orbi) with one satellite in each floor of the house, to ensure each of my Players always has very powerful signal. The Support Crew also assigned a an IP address for each of my Players - that did not solve my problems at the time but it's a relatively easy thing to try and see if that helps you.

    Good luck!
