After I installed the Realtek audio driver on my MacBook under Windows 7 Beta, I could hear music just fine. However, I found that I could not record anything through the microphone. I checked my other MacBook under Vista, and the microphone didn’t work, either. I checked another laptop with Windows 7 Beta, and still, the microphone did not work. I then realized that none of the built-in microphones under Vista and Windows 7 Beta worked.
Some tweaking about the microphone properties got it to work. Here are the steps:
- Click on Start (the Windows icon) and type sound.
- Click on Sound under Control Panel.
- Click on Recording tab. Select Microphone and click on Properties.
- Click on Levels tab. The default Microphone Boost is set to 0. Increase it.
Close all the dialog boxes, and the microphone will be ready for use.
[Note: Not all drivers have this settings. I have tested this on Realtek and Sigmatel drivers]
