Make sure you have the proper Windows 10 driver. Then:
Right click the Windows Start button and choose Device Manager.
Click on the Carat next to Sound, Video and Game Controllers to expand it.
Right click on the current sound device and choose uninstall.
Under Action on the menu at the top choose Scan for hardware changes.
You can opt to allow Windows to find the proper driver, but I suggest you choose the "Have Disk" option and install the proper version.
