Realtek 97 mic/line-out switched

[dsync0]

my mic in and line out have been switched. ive heard of this problem many times but i forgot how to fix it. my mobo is Asus P5ND2-SlI Deluxe with the Realtek 97 on board audio. i have checked the bios to make sure the audio card was enabled, and it is.

mo info for my mobo: P5ND2 SlI
says its a Realtek ALC850 7.1-channel
