Hi:
See if this driver works.
If it doesn't install automatically, try a manual install by going to the device manager, click on the audio device needing drivers.
Click on the driver tab. Click on Update Driver. Select the Browse my computer for software method and browse to the driver folder that was created when you ran the file.
That folder will be located in C:\SWSetup\sp35558.
Make sure the Include Subfolders box is checked and hopefully the driver will install that way.
