Hi Kalana,

I am sorry but we could not find out the cause of the issue. Please try reinstalling driver again by following steps:

Uninstall the audio driver.
Restart your computer. (Nam Nguyen did not mention this step).
Install the driver again.

This solution worked for some users in the past. Hope it also works in your case.

Regards,
