Download Realtek HD Audio Driver 2.70 for 64-Bit Vista, Windows7, Windows8 (x64)

Because having the correct audio drivers is critical you should make sure to download Realtek drivers if you have a motherboard with a Realtek audio controller (most motherboards do)

This audio driver is for HD sound and works on Windows Vista/7/8

Stop: Please Verify You Have A HD Audio Controller

Before you attempt to install this driver, please verify that you have a High Definition audio controller. You can do that by opening the Windows device manager and checking your audio controller

1. Step Open the Control Panel

2. Step Click on Device Manager

3. Step Uncollapse Sound, video and game controllers

4. Step If you see either AMD High Definition Audio Device or a High Definition Audio Device listed, then you have HD support. If there is no HD device listed, it does not necessarily mean you don’t have a HD controller but it’s very likely because Windows auto-installs most audio controllers

Should you run into any problems, post a comment. Realtek drivers usually are very stable and are updated frequently, so check back from time to time to see if there is an update
