Listen with headphones first. If the volume is turned up or down, there is something wrong with the computer sound card. If you hear loud sounds from left to right, you can be sure that there is something wrong with the speaker.

Voice conversion line

Change an audio cable. After testing with headphones to ensure that the audio cable and sound card are normal, remove the headphones, connect the computer with the speaker, right-click the speaker, turn on the volume control, and pay attention to the balance between the left and right speakers. Be sure to turn up all the volume in the middle to see if there is any change in the speaker volume. If it's still an old problem, it's a problem with the speaker. If this happens, I suggest you change the subwoofer.

Good sound source test

The premise is that the music you play must have good sound quality, preferably in MP3 format. Baidu downloads some good music, because the sound source must be good, so you can listen to more songs.

Super bass sound combination set

If this happens, I suggest you change the subwoofer. At present, the subwoofer sound combination set in the electronic market is very cheap. You can buy a pretty good stereo around 200 yuan. If you want to choose it, please. Listening is the most important thing when buying. Buy it when you feel better. You can't just ask for a loud voice. You know, sound quality is much more important than sound.

Power socket and computer software settings

First of all, make sure that there are no other high-power appliances on the power socket of the speaker, which can be plugged into the same plug-in board as the power supply of the computer. Secondly, your computer software is set up. Right-click the speaker, turn on the volume control, and check "Mute" in the "Line Input" item, that is, cancel the line input sound to see if there is any current sound.
