7] Install an Alternative Compatible Audio Driver Version¶

If updating to the latest audio driver does not resolve the issue, sometimes installing an older or alternative compatible version of the audio driver can be effective. This can be helpful if the latest driver version has introduced new bugs or compatibility issues with your specific system configuration.

Before proceeding with this step, it is highly recommended to create a System Restore Point. This allows you to easily revert your system back to its previous state if installing an alternative driver causes further issues. To create a system restore point, search for “Create a restore point” in the Start Menu and follow the on-screen instructions.

1. Open Device Manager. (Refer to step 1 in section 2 for instructions).
2. Expand the Sound, video and game controllers category.
3. Right-click on your audio device and select Update driver.
4. In the “Update Drivers” window, choose Browse my computer for drivers.
5. Select Let me pick from a list of available drivers on my computer.
6. In the next window, ensure that the “Show compatible hardware” checkbox is selected. This will filter the list to show only drivers that are considered compatible with your audio device.
7. You will see a list of available drivers for your audio device. This list may include different versions of the driver.
8. Select an alternative driver version from the list. Try selecting an older version than the currently installed driver.
9. Click Next. Windows will install the selected driver. Follow any on-screen instructions.
10. Restart your computer after the driver installation is complete.
11. Check if the audio issue is resolved after the restart.

If installing an alternative driver version resolves the issue, it suggests that the previous driver version might have been incompatible or buggy. If the issue persists or worsens, you can use System Restore to revert back to your previous system state and try a different driver version or another troubleshooting method.
