Read this fully so you don't screw up

:
So, I'm too lazy to sign up and what-not. But, just to give you guys some information on this problem, I'd like to say that she's not completely stupid because I've been having this problem for quite some time. My sound just stops working and then I fix it and then later it eventually happens again. Also,
yes, I have a Toshiba Satellite laptop. I'm actually very good with computers (I program and do web design [Visual Basic, C++, HTML, CSS, PHP, etc]), so you can trust me it's not your "common" problem. I actually think it
must be a problem with Toshiba laptops themselves (or at least the sound card/software they provide maybe), or maybe just how they work with Windows XP. First of all, try going to
http://www.microsoft.com/directx. Download DirectX 9.0c and install it. It will require you to reboot. If this doesn't fix your problem, you can try getting a program called DirectX Eradicator or a similar working program to completely uninstall DirectX (Microsoft doesn't give you an uninstaller). After uninstalling, you can then reinstall DirectX (this is what usually works for me). Unfortunately I've been using this fix with 9.0b, not 9.0c. So, if you can find 9.0b, you may want to try that instead. Sorry I can't provide links, I'm just
that lazy. Anyway, after 9.0c I can't seem to do this same workaround, so I'm currently searching for another fix. There's another problem I've heard of with Toshiba laptops and sound that's apparentely some drivers under the name "ALi" something. Apparentely you can locate these under the "sound, video and game controllers" section of your Device Manager. Since I didn't see that when you wrote out what you saw, I'm assuming you have the same problem as I do. I hope this will help you solve your problem. Personally if you can get DirectX Eradicator and DirectX 9.0b, you may want to try that first. Like I said, that's how mine was corrected. Remember both require you to restart, and I think you actually have to restart after each separately for it to work. Good luck, and if anyone has a similar problem with a quicker fix or a long-term fix so they sound won't stop working, post it.
