Hi , please can someone help me out I downloaded service pack1 software for my window vista and installed it after installation i found out that my audio output had gone i tried searching for the driver to no avail please what do i do?

My friend the advice i would give you is to download a software called (Drivermax), Just google it and download it, After u install it then u need to register for your registration code by email to activate the software, its totally free, After activation the software will automatically search for drivers required for your computer model, From there your can update all your drivers and that should fix the Audio problem that u are having,
If that fails and u really need your Audio output back then go to control panel and uninstall the Sp1 from the list of installed updates, After uninstalling Sp1 and your system will be back to normal.
Cheers
