1. If you have just reinstalled the operating system, make sure that the driver for your sound card is installed correctly. Usually when we are equipped with a computer, we will give some CD-ROM, there is a sound card and the motherboard driver. If not, we can go to the Internet to search your motherboard model corresponding to the sound card driver download and install. The way to see if the driver is properly installed is to right-click on the desktop My Computer icon, click Properties, Hardware tab, Device Manager, and then see if there is an exclamation point or red Cross in the sound card item. The main reason why the computer has no sound is that the driver is not installed after reloading the system.
2. Please ensure that your speakers are plugged in the power supply, general speakers will have power indicators, if the light is not bright, the speaker power is not plugged.
3. Please make sure that you have plugged the speaker socket or headphone jack into the computer host and plugged in the correct position. Many people plug the speaker or headphone jack into the microphone socket. Speaker of the socket line is generally light green, the host on the Jack is also light green, we need to color the same line inserted in the same color of the jack. Often have users ask us how the computer does not sound, how to do. We give them Remote assistance, found everywhere is right, after a careful question to know the original plug in the wrong position.
4. Turning the volume to 0 is also the main reason many people think the computer has no sound. Some people turn the volume on the speaker or headphone line to 0, so of course you won't be able to hear the sound. In the lower right corner of the computer screen there is also a small volume icon, where you can also turn the volume to 0 or mute, we also want to ensure that this is not 0 and mute state. There is also a place on the player that adjusts the volume, and these places cannot turn the volume to 0. Otherwise, of course, it will cause the computer to have no sound.
5. Speakers or headphones broken is also a cause of my computer no sound. If you have a lot of speakers or headphones at home, you can give it a try. If you find a sound when you change it, it means the sound equipment is broken and you need to repair it or buy a new one.
