Hey there.

I noticed my light going on in the ts3 app for no reason. Soon enough the people on the server asked me what that crackling noise is that comes out of my microphone.
The noise kinda sounds like you plug in a microphone but even when there is no mic in the smartphone it still makes those crackling noises.

They come pretty random but still too many times so you can't ignore it. Neither the sound itself, nor the volume of the sound is ignorable.

I did a voice recording for 10 minutes with and without saying something time to time. I didn't get that sound a single time in that recording so I think that there is something wrong with either the app itself or a setting on my smartphone combined with teamspeak.

I have a Honor 9 smartphone by the way.
