Macbook audio problem

Since I installed Windows 7 on my MacBook pro I was not able to get the audio to work. The problem lies with the audio drivers. Windows 7 automatically installed generic drivers which do not work. You can easily verify this by the output of the audio channel. If it lits up red, it means it is not configured correctly.

The problem can be solved, but depends on type of MacBook you own. The audio card in your MacBook varies with the type. There are three different drivers for the different audio card vendors:

1. Realtek
2. Cirrus
3. IDT SigmaTel

All drivers can be found on the installation disc of Mac OS under the directory bootcamp/drivers. Depending on the audio card that is in your MacBook you have to install the correct driver.

The setups of the drivers might give a problem. This is due to the compatibility on Windows 7. You can solve this by a right click on the setup and select compatibility troubleshoot. Then you have to select Windows Vista as compatible version. After installing the right driver everything should work fine.
