What should I do if the sound of the speaker suddenly becomes smaller?

The sound of the speaker suddenly becomes smaller, which is very annoying. This paper will introduce the method to solve this problem.

Restore the original state of the volume equalizer.

Restore the original state of the volume equalizer. If the problem has not been solved, see 2.

Check the speaker tuning button.

See if the tuning button of the speaker is loose (of course, it will only affect if it is loose, and there will be no problem if it is separated from the speaker). If it is loose, try to see if there is an optimal contact point. Of course, it is best to set the volume and channel switch button to the middle. (If it is not loose, see 3)

Check the speaker and the wires behind the speaker.

See if the wires behind the speakers and speakers are damaged, and if so, replace them. It doesn't matter. (unresolved, see 4)

Play music and check the sound card.

Find a piece of music or something to play If the breakpoint or the sound is suddenly high or low, it doesn't mean that your sound card is ok. (Don't worry _) If it is, it will cost you money (-! )
