If your computer is a notebook or brand machine, you can go to their official website to find the same model of sound card driver ** as you install it, if it is compatible with the machine, you can automatically search for the sound card driver installation under the next driver wizard and other software, it stands to reason that when you buy your computer, it is equipped with a driver disk, and the motherboard driver is together, you can install it directly with a disc.

You can update the sound card driver in the device manager, see if there is a driver on the computer, and if so, it can be installed automatically.

Check if the volume is not turned on [turn on the small speaker in the lower right corner], if it still doesn't work, try it with headphones. The headphones can be used, but the speaker is broken.

Then it should be a microphone problem, after you go to the sound settings, disable the microphone you are using now, and start another one.

The waveform volume is on, the line volume and the microphone volume are off, try it, it is estimated that you are the waveform volume or the main volume is off.
