What should I do if the USB speaker has no sound but only the sound of electricity? How to solve the problem when the small speaker is not responding when plugged into the computer?

Symptoms:

After plugging in the USB speaker with the built-in sound card, there is no sound from the computer, only a weak sound of electricity, or the sound is the sound of the laptop's own speaker.

Solution:

Troubleshoot USB interface and audio quality issues

1. You can try the USB interface and audio with other devices or computers without any problem;

2. Make sure that the sound playback source produces normal sound;

3. You can find a piece of music that has been played normally before, etc.;

4. Find the Control Panel in Start and open it;

5. Click Sound, Voice and Audio Devices;

6. Click to change speaker settings;

7. Click Audio in the upper left corner;

8. Select the item with the USB name in the drop-down list of the default device for sound playback;

9. Click Apply in the lower right corner - OK.

There is no sound in the USB speaker, only the sound of current. This is because the small speaker has no problem in producing sound. The reason why there is sound of current is because the USB power supply causes the speaker of the small speaker to resonate. The sound will be relatively small, which is normal.
