Some audio problems might be caused by an issue with the audio system’s IDT High Definition Audio CODEC. This can be fixed with a manual driver update which allows you to choose the sound driver you want to use. 

Note: Not all systems will have an IDT High Definition Audio CODEC. 

To check and see if you have one, and to manually update the driver 

  1. In the search box on the taskbar, type device manager, then select it from the results.

  2. Select the arrow next to Sound, video and game controllers to expand it.

  3. Look for IDT High Definition Audio CODEC. If it's listed, right-click it and select Update driver,  then select Browse my computer for driver software > Let me pick from a list of device drivers on my computer.

  4. You’ll see a list of pre-installed drivers. Select High Definition Audio Device, and then select Next.
