Apple’s Boot Camp Assist 1.1.2 b includes SigmaTel audio driver for MacBook. However, when I first installed it, the microphone was not working.
I first thought the microphone driver is not compatible with Vista. Later, I found that it’s not a compatibility problem. The microphone is just not enabled by default. Here is how you enable it.
- Open up Control Panel. Go to Ease of Access.
- Click on Set up a microphone.
- Follow the wizard to set up your microphone as a desktop microphone.
