  • In the search bar, type “system restore” (no quotes).
  • Select Create a restore point.
  • Navigate to System Protection.
  • Choose the drive you want to check and click Configure.

After you have created a restore point, we can proceed to the first solution.

Option One: Update the Multimedia Audio Controller Driver

An outdated driver can be the cause of many problems on your PC. It is, thus, very important to keep your system drivers up to date. There are two ways in which you can go about updating your multimedia audio controller driver: you can do it manually or automatically.

Updating your drivers manually is typically recommended for more experienced users. You will need to locate the outdated drivers yourself, download the latest available versions from the manufacturer’s website, and install them on your PC. This can be quite a time-consuming process. Plus, if you do make a mistake when updating your drivers, this can result in more and bigger issues for your computer.
