strange high pitch whining noise on the background

    Hi guys, back on July I've bought a Blade Mid 19 OLED and today I was testing some recording application and I've noticed that the microphone was capturing a high pitch whining noise on the background, you can here the noise in the following link:

    https://voca.ro/omWPph9jEHi

    I am not sure whether this issues was since then or not but to be honest with bare ear it is hardly noticeable unless you really give focus on it or if you have high sensitivity to these kind of noises (actually from time to time unconsciously I can grab it to my ears). However, the issue comes when you start recording where it really get noticeable.

    I am not sure whether it is due to coil whine since it seems to be periodic and comes and goes any idea what this could be and how to be resolved.

    I am with the latest updates and bios (v1.04) if that makes any change.

    Update:

    Ok, after some further testing it seems that the noise goes away once I unplug the power cable.

    You will have to put your ear all over the razer and mains adaptor to see if you can locate it.
    If its just the built in microphone then try an external mic or a mobile phone to see if it can pick it up at the same location as the built in one.

    @iDATUS thanks for the reply. I was in touch with the support and then they asked me to apply the recovery systems steps (Boot --> F9 --> Start recovery --> etc). This seemed to work temporarily since exactly after the recovered new system I was not getting any noise from it. However, after a while it came back. Then I though that it might was some windows update that caused it come back, thus reapplied the recovery, disabled the windows updates since I did not have time to check which update might be causing the issue and for a day or something I did not have this annoying noise anywhere. Today I had to reboot, and guess what after that the noise was back again. Tried again the recovery steps but this time no luck. To be honest it seems to be randomly coming and going. I've made a video about how to reproduce the problem (I've also played a bit with the mic boost), which can be watched below:



    Also if you notice now the noise shows up even if I remove the power source. However, after another reboot it is not there:



    At the moment I can hear it. I do not know what the heck is causing this noise it is really annoying and I am not sure whether it is a hardware issue at the end.

    Thanks for the effort in reply.
    Sounds very much like feedback, like the mic is auto gaining, hits a high and throttles back.
    Turn the mic down and hopefully that cures it.

    To me it seems that mic is auto echoing or something (could be a possibility that there is some coil whine from something that is close to the internal mic and there you have it), in any case disabling/muting/turning the level down on the mic did not help, if I put close my ear I can still hear it buzzing. I will contact the support again, and lets see.

    Ok, wasn't sure if it was just the mic picking it up. So you saying the noise is there all the time/
    Can you do me a favour, load task manager and wait till the cpu and disk usage is very low if not zero.
    Change update speed to slow as well.
    When its idle do you hear the sound?

    Yes the noise is there despite the mic is on/off (but it becomes a real problem because when I need to use the mic it amplifies the effect, so while I am talking to people they hear this whining noise in the background together with my voice which of course is disturbing). I will try what you are saying once I reboot on Windows (currently I am working on Linux, where the problem is also showing up, also when the cpu is iddle and not applying any disk usage, it is ssd anyways).

    SSD is noisy as well. It sounds about 1/3 - 1/2 of what an SSD noise can make.

    @iDATUS I did not replied so far since two days now everything works fine (I do not know how/why) but no noise at the microphone anymore since the last time that I've written here. Could be some software update or something I noticed quite a few the last days. Anyways for now no problem.
