No sound from computer? It is an annoying problem which bothers thousands of computer users. I got this problem once. When I used windows media player to play a video, but there was no sound from computer. Fortunately, I fixed this problem finally.
How I fixed this problem? Before I tell you the method, I would like to tell you the usual issues which cause the problem. One factor is the sound card problem and another is the driver. You should follow the steps below to fix the problem. (The process may be a little different between Windows XP and Windows Vista. )
1. Check Your Sound Card
1) Check the Sound Card.
Firstly, you should check out if your sound box is working. If your sound box is working, then check out your sound card. If it is attached close to the socket;if the chipset is still working?
2) Check BIOS Setting.
If you are using on board sound card, you should check your BIOS. When you enter BIOS, open Integrated Peripherals and find your sound card(normally its name is AC97 Audio). Then set it to be Auto or Enable. Then find On Board AC97 Control and set it to be Auto or Enable. Save and exit.
If all those issues are all right, but still no sound on computer, it must be the problem of the driver.
2. Check the Audio Card Driver.
1) Open Device Manager.
Right click My computer and Properties. Then the Properties Window opens and click Hardware tab. Click on Device Manager. The Device Manager will pop up.
2) Check the Audio card.
Click "Sound, video and game controller". You will see a list of items, if there is a red cross before an item, it means this item is disabled. Then you right click it and set it to be Enable.
3) Driver is corrupted or outdated.
If you see an exclamatory mark before an item, it means that the driver is corrupted or outdated. So you need to install a new driver for it.
Normally corrupted or missing driver files cause the sound problems. The best way is to back up and update your drivers regularly.
