Whilst trying to repair a dell PC's sounds issue I found this info .

"Did you know that unless you uninstall a device driver on a Windows XP machine that it still may be sucking up valuable system resources? Here are step-by-step instructions on how you can view and remove these unnecessary devices."

I have tried these directions and they work! As always, make a restore point or backup the registry just in case. Even if you do accidentally remove a device driver that Windows is using, it should detect it on the next reboot. FYI: It is clearly visible which device drivers are in use just by the look of the icon.

1. Press [Windows]+[Break] to bring up the System Properties dialog box.
2. Select the Advanced tab and click the Environment Variables button.
3. Click the New button below the System Variables panel.
4. In the New System Variable dialog box, type devmgr_show_nonpresent_devices in the Variable Name text box and 1 in the Variable Value text box.
5. Click OK to return to the System Properties dialog box and then click OK again.
6. Select the Hardware tab and click the Device Manager button.
7. In Device Manager, go to View | Show Hidden Devices.
8. Expand the various branches in the device tree and look for the washed out icons, which indicate unused device drivers.
9. To remove an unused device driver, right-click the icon and select Uninstall.

I followed these instructions and got the sound working on the Dell I was repairing :banana: .( Lucky coz the piece of sh1t computer was about to get a good kicking)

I then tried it on my home computer which has had many upgrades. I found sh1t loads devices remnants.

Hope this comes in usefull to someone out there :) :BLOBBY:
