In fact, the method is very simple. The reason for the harsh sound is that the sound emitted by the built-in microphone of your computer and the speaker are connected, which produces a whistling sound, also called self-excited oscillation, forming a harsh sound.

Solution (taking Win7 as an example):

Click the small speaker on the right side of the stand-alone taskbar and click Synthesizer. Select System Sound in the dialog box that pops up, then select the Recording tab - Microphone - Properties, then turn down or mute the microphone sound, and adjust the microphone boost to 10 decibels or the lowest, so that the harsh sound can be improved. If you mute it directly, there will be no harsh sound at all.

If it has not been adjusted, it may be when you unplug the headphone jack. inThe wires fell off causing interference. If this is the case, you need to take it to a repair station for repair. If it is within the warranty period, you only need to say that the laptop suddenly encountered this problem, and you can enjoy it for free. If you are out on parole, find an ordinary repairman and it will cost you thirty yuan.
