Solved Toshiba Satellite L450-D built-in microphone problem!

Hi everyone! I am a new member to windows 7 forums and I came here having a problem with my built-in microphone on Toshiba Satellite L450-D laptop, so here is the story: :sarc:
I used to have installed Windows 7 Proffesional on my laptop and the built in microphone was working perfectly but after upgrading to Windows 7 Ultimate my built-in microphone stopped working!
I tryed going into Recording Devices and enabling my microphone but no help it still doesn't work!I mostly use my microphone on skype chat so I need help! I hope for a fast reply

Take a look at your device manager to make sure the correct drivers are installed. If not, head on over to Toshiba's website and download the audio drivers from there.

Thank you ben for your reply but I already solved it before you replied!
Thanks anyway
