Starting a new thread confuses the issues. Place a link to your original post.

"Place a link to your original post." As in like so http://www.computing.net/answers/ha... Assuming there's nothing wrong with the mboard, and you downloaded the proper drivers for your exact model and mboard version (there may be several mboard versions - look for the version number or revision number printed on the mboard), these are the only other things I can think of.... Look in your bios Setup and make sure the onboard audio is enabled. If you also have a sound card in a slot, Windows supports more than one sound chipset on a computer, but only one can be used at a time. You can change which one is used in Control Panel - Sounds and Audio Devices - Audio tab. You can select which ine you want to use by clicking on the down arrow at the ends of the boxes.
