I tried to record some music with my laptop microphone and external microphones, but aside that these are different, the effect is the same (external ones work good on my stationary PC);
What I mean that it lowers input strength after 1 second. If I play single, stable sound that should not change in volume (organs), the input results in something like this:
It always happens at the same time of sound length, about in a second.
I use OBS and windows built-in Voice Recorder. There are no programs that would change microphone strength, because it happens also in Microphone Listening mode. I disabled changing microphone volume in settings anyway. What could be cause of this? I'll provide any additional information.
