My name is Debbie.
There are two options for uninstalling Audio driver Through Programs and Features and Through Device Manager. You can click on the URL mentioned to follow anyone procedure out of those two: http://www.vistax64.com/tutorials/171469-uninstall-device-device-driver.html
For Driver INSTALLATION, you can either visit the website of the manufacturer of the sound card you are using or to your computer manufacturer website to install the latest audio driver.
Please reply in case you have any questions.
Thanks & Regards
