There are two ways you can get the right audio driver: manually or automatically.

Manual driver update – You can update your audio driver manually by going to the manufacturer’s website and searching for the most recent correct driver for your sound card and your variant of Windows 10.

2) Run Driver Easy and click Scan Now. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to a flagged audio driver to automatically download the correct version of this driver, then you can manually install it (you can do this with the FREE version of Driver Easy).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)

4) Restart your computer and check to see if the problem is resolved.
