How to Fix ACM Driver Errors

By Charles Poole

The Audio Compression Manager, or ACM, uses a driver to allow users to edit and listen to audio files on their computers. If your ACM driver isn't working properly, Microsoft recommends that you follow one if not all of the three techniques used for device driver troubleshooting. These three techniques include reinstalling your driver, updating your driver and rolling back your driver. You don't have to be Microsoft certified to complete this task. You can do it with minimal knowledge of the subject.

Log in to your computer as an administrator from the "Welcome" screen when you turn your computer on.

Step 2

Step 3

Click on the "+" sign in the "Sound, video and game controllers" section. Right-click your "ACM" driver and then click the "Uninstall" tab in the menu that appears.
