Hi guys, i am using manjaro xfce with kernel 5.10.49-1 LTS. my computer is acer aspire e15. my microphone, whenever i joined a video call or a conference call online , it will create a fan-like noises like a fan points straight into the microphone. it creates echo sound multiple times until it got high pitch which is unbearable.
I dont think this problem is related to hardware because when i use recording using web browsers or applications it worked flawlessly (still the built-in microphone).
Can anyone help me to debug and find the root cause of this problem? I dont know where to start. (I have follow all the guide from archWiki, including settings like echo/noise cancellation and stuff)
I can only assume that you are in fact using two different microphones. You said you are using something like noise cancelling and other effects which may create a virtual microphone that is used for the recording applications but not the chat applications.
That happens at least for when you gain the volume in pulseaudio over the base. That seems to be normal. On WebRTC which is used in webbrowsers and electron apps, there must be an option to use echo cancellation and noise reduction.
