After we used the YuLinMuFeng win7 operating system, some friends encountered a situation where the computer system had no sound when entering the operating system. So the editor thinks that this problem may be caused by some kind of failure in the sound card driver during the system installation process of our computer. You can try updating the driver or reinstalling the system. Let’s take a look at the specific steps to see how the editor did it~
1. Press the win r key combination on the keyboard to open the run window, enter services.msc
2, then find "Windows audio" in the opened service window and double-click to open it.
3. Then check whether it is running normally. If not, click "Start". Change the startup type to "Automatic".
4. Right-click the mouse on the computer, click Management, and click the Services and Applications option.
5. Click Services, find Windows Audio and keep it started.
6. Return to the desktop, open the Control Panel, open Hardware and Sound, and click Sound.
7. Double-click the speaker to open the properties window, click the level option above, and the speaker will be in the normal state.
The above is the detailed content of How to solve the problem of no sound after installing YuLinMuFeng win7. For more information, please follow other related articles on the PHP Chinese website!
