I recently was updating some of my Drivers on my laptop (a hp Pavilion g6) (upgraded to windows 8 from 7), all of the update worked fine until it came up to my Audio, it ended up Stopping my Audio from working and now it will no longer play sound, the speaker icon has a red cross on it and when i hover over it, it says "No speaker or headphones are plauged in. The Program i used to update my drivers is "Slim Driver" i tried other Driver Programs to fix my audio problem but it sill wouldn't work. I looked in my Device Manager and it turns out "IDT High Definition Audio CODEC" is the problem and needs to be re installed or somthing when i go into it there is a message saying "Re-install the drivers for this device. (Code 18)" and underneath that a button to re-install it but when i press it, it doesn't work. Dose anybody know how to fix this problem i would really apreciate it.
