Quite likely you need new drivers. And an uninstall of the old drivers first. (In your case, audio drivers)
Check the OEM Support site for your device and/or the hardware component. Download new drivers if they can be found... Open Device Manager and expand the component category.
Disable the device and uninstall the drivers for it. Reboot. Run the driver install utility you downloaded from your OEM. Reboot, even if it does not advise you to...
