HELP

!!! ~ For some reason, after I installed either SP2 or one of the other critical fixes, my audio devices stopped working. I have uninstalled and reinstalled the hardware in device manager (no luck), formatted C: and reinstalled XP with no luck also. The audio device appears just fine in the Device Manager, but in the Sounds and Audio Devices Control Panel I kept getting the "No Audio Devices" message. All options in this control panel item were grayed out. I've even done an XP "System Restore" to a time before I installed the Windows Update. This worked fine and rolled back the changes ... but still the same nonsense with the Audio remains. When rebooting the computer I do hear the initial beep, but that is it! I am also unable to even access the system volume and receive the following message:
Error Message: (when attempting to adjust the system volume)
There are no active mixer devices available. To install mixer devices, go to Control Panel, click Printers and Other Hardware and then click Add Hardware.
