No audio device Installed? Many people get this error message when they try to play music or video with Windows Media Player or other players. And there is no sound on computer at all. Why does this error happen while the audio card is already installed?
There are many factors can cause the error. You can follow the steps below to fix this errors quickly.
1) Examine BIOS Setting.
If you use a onboard audio card, you need to check the BIOS setting. Restart your computer and enter BIOS, open Integrated Peripherals and find the audio card(normally its name is AC97 Audio). Then set it as Auto or Enable. Then find On Board AC97 Control and set it as Auto or Enable. Save and exit.
If the problem still exists, you should follow the step 2.
2) Check Device Manager
a) Right click My Computer and then Properties. Click Hardware Tab and Device Manager.
b) Check "Sound, video and game controllers" item. If there is a cross icon on any sub item under it, then right click the sub item and choose Enable.
If there is no cross icon but a Question mark or Exclamatory mark, it means the audio card driver is installed improperly or damaged. You will need to reinstall the audio card driver. But most of the time, the Device Manager cannot detect errors of the devices. You should go to step 3.
3) Reinstall/Update Audio Card Driver
In fact, up to 60% of the "no audio device installed/found" errors result from damaged or corrupted sound card driver. If the driver is corrupted or damaged, Windows will not be able to recognize the sound card and computer probably has no sound at all. You need to reinstall and update the sound card driver to fix the problem.
