You just installed Windows 7 onto your Intel-based Apple computer but there is no sound. Why not?
This is a known issue with Boot Camp and Windows 7 and there is a fix.
- While booted into Windows 7, insert your OS X Leopard DVD. When prompted, select Run setup.exe. If AutoPlay does not prompt, go to Start | Computer and right-click your DVD Drive to Explore the DVD, then double-click on Run setup.exe.
- The Boot Camp installer will launch. Click Next to begin.
- Select I accept the terms in the license agreement and then click Next again.
- Make sure that Apple Software Update for Windows is checked, and click Install.
- The Boot Camp installer will install all the required drivers.
- Notifications may pop-up with each driver that gets installed.
- Once completed, click Finish.
- You’ll be prompted to reboot. Remove your OS X Leopard DVD from the drive, and click Yes to restart back into Windows 7 to verify that you have sound.
- If you still have problems with sound not working, you’ll need to install the Realtek drivers. Install the latest (2.14) Realtek Drivers onto Windows 7. Select the High Definition Audio Codecs (Software) link, accept the license agreement, and after the download has completed run the executable. You may need to reboot your Mac back into Windows 7 for audio to work.
