I was capturing audio using alsa/pulse, or even without any microphone. But always i have this sample static noise.
Similar to those (you can hear the exact noise what i have now):
How do i kill such noise, even without using any microphone?

1) PC1: alsamixer i mute all my mic 2) PC2: i connect my laptop speaker-out to PC1 microphone in 3) PC1: volume 100% 4) PC2: i hear sounds of PC1 That really proves how blindly he is capturing any kind of noises.
