i had got a barebone kit, and everything was easy to install except for the lights for the case, and the on board sound card. i'm not sure if there is something on the mobo that i didn't plug in, or a jumper that wasn't plugged in the right slot i don't know. i know it's not installed right because when i go to my device manager, it shows the yellow exclamation point by the sound card. is there something that needs to be plugged in or is it just a faulty mobo. everything else works great on it (cpu, ram, firewire, usb). this is the mobo i got: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?Sku=B450-2206
If you can see the on board sound card in the device manager it is working. You need to install the drivers for the sound card. You should have gotten a CD with the mobo that contains the correct drivers.
nice, it works! it is set to auto in the bios, but then i went and got updated drivers for it all and it installed thanks guys!
