Check whether the equipment is normal.
First, check whether the sound card, cables, speakers and other equipment are normal. Then open the device manager to see if there are any abnormalities in sound, video and gamepad.
View Windows components
If the speaker is missing, open the control panel, enter the audio and video equipment, find the volume option, and check "Put the volume icon in the taskbar". If there is still no sound, try adding or removing Windows components and reinstalling the necessary audio components.
Check the microphone settings.
In addition, when there is no sound in the microphone, double-click the speaker, enter the properties, find the microphone option, and make sure it is checked. If you enter BIOS settings when you start the computer, make sure that the sound card is set to automatic or enabled.
Follow the steps
By following these steps, I believe that the problem of no sound in your computer can be solved. If you have more questions, please consult a professional.
