Windows 7 and 8.1 are now obsolete if you have these Operating Systems you should use them to take the Free Upgrade to Windows 10.
If you don’t have a Windows 7/8.1 license you have until the 2nd of October 2015 to upgrade to Windows 10 for free using the Windows 10 Insider 10130 as a stepping stone. See Free Upgrade from Windows Vista to Windows 10 (also works with Windows XP).
Try in order latest first, if it doesn’t work try for an older version.
For Windows 8.1 the audio driver is inbuilt to the OS and the registry file or older Sigmatel Driver should not be installed.
Install the registry file and then the audio driver. New untested.
