Upgraded old Inspiron 9300 to Window 8 - Lost Audio Drivers

Is there any error in the device manager? If so what are the hardware IDs? See here for details: http://dellwindowsreinstallationguide.com/downloading-drivers-checking-hardware-ids-and-downloading-and-installing-dell-system-drivers-in-the-correct-order/checking-hardware-ids-in-the-device-manager/

I looked on that site you referred and the code shows it as Intel because of 8086 on the Hardware IDs. "PCI\VEN_8086&DEV_266E&SUBSYS_01891028&REV_03
PCI\VEN_8086&DEV_266E&SUBSYS_01891028
PCI\VEN_8086&DEV_266E&CC_040100
PCI\VEN_8086&DEV_266E&CC_0401"

I tried to install the Intel utility for Windows 8, but it didn't do anything. (Do I need to uninstall the current Multimedia Audio Controller first?)

I still have the same error and it doesn't automatically find any drivers to update the Multimedia Audio Controller. I appreciate the previous help and any other ideas are greatly appreciated. Otherwise, I'll have a laptop with no sound, but I've seen that others on Youtube have updated Windows 8 or 8.1 on these old Inspiron 9300.

"The drivers for this device are not installed. (Code 28) There are no compatible drivers for this device. To find a driver for this device, click Update Driver."

Try to install SIGMATEL STAC 975X AC97, v.5.10.0.4255, A03:

If it doesn't work installing directly then install via the device manager following the instructions here:
