Hello! Welcome to Windows7Forums.com

I'd suggest updating to the latest generic Realtek drivers (2.70). You can get them from here: Realtek (have to check accept and press next).

Hmm i only tried download realtek driver to boost microphone but i forgot to one thing.Lots of times back i had problem with audio,when I spoke with friends on skype it got loud background noise and i cant be heard.i put my computer to shop for repair .. they already repair it and is ok but I cant use realtek now.So i think i need new driver but don´t know what.And again sorry for my english.
