[SOLVED] Hi guys, After a reformat yesterday due to a new hard drive everything was fine, I then couldn't understand why the sound suddenly disappeared. Reading a post on the net after trawling for hours it has become clear that when Service Pack 2 went on all the sound disappeared. I looked through the device manager today to find that "Plug and Play software device Enumerator" has a yellow exclamation mark by it. With the properties: "This device is not working properly because Windows cannot load the drivers required for this device (code31) I located the swenum.inf file on the Internet which is the drivers for this device so I have tried to reinstall but each time it turns up with this yellow exclamation mark. I've reinstalled the drivers for soundmax from the Toshiba CD as well as downloading the fresh .zip for the sound card from their website. System Info: Windows XP Home Celeron CPU 2.60GHZ 496 RAM Toshiba Satellite A40 So after a lot of searching and no answers, I decided to restore back to Service Pack 1. Sure enough on boot the sound was all working and the Enumerator under System was working no probs. So I then run Windows Update yet again, after another 3 hours of downloading and installing, service pack 2 was for the 2nd time applied to my system. On reboot, yes all the sound has disappeared and I am back to square one with the Enumerator having problems. Any help would be greatly received, thank you in advance!
