Right-click the small speaker--Adjust audio properties--Audio--Recording volume, line volume and stereo mix and select mute (well, it seems that you only need to select one, but the mute effect is the same anyway = =I'm just passing by OTZ) After selecting mute, the sound from the computer should not be recorded.
I don’t quite understand about “even the loudspeaker does not play the microphone sound” = =. . . Does it mean that when you speak into the microphone, you will hear your own voice in the headphones? I can only talk about my personal situation. If I turn on the microphone enhancement, I can hear my own voice, but if I turn off the enhancement, I can't hear it...
