My HP mini's sound isn't working, help?

I have Windows 7 Starter. My HP isn't having any sound through the speakers recently. I've tried re-installing it's driver IDT High Definition audio CODEC and running those pointless troubleshooters both online and off the computer itself, nothing worked while saying 'fixed it'. Though the troubleshooter I used off the internet download said that it detected a hardware change and it fixed it. I'm not interested in calling in an HP technician for maintenance, I rather do this myself. Although it worries me that I have to open the computer and see what's wrong inside it which I wouldn't like to do because this computer is at constant use... And for the fact that I'd hate to accidentally break it.

Although if it's the necessity to do things I rather not, I'll take it as a best answer. But I rather find another away around...

Got any ideas guys? Thanks for reading and I appreciate all help!
