Ok thanks for everyone's help I fixed it. Here is how, though:

1) Went into BIOS and went to the Onboard Devices Manager
2) Went into 97'Audio Controller and switched from [Disabled] to [Auto]
3) Went to esupport.sony.com and downloaded driver
4) Installed driver and rebooted

Works fine now. I never thought of checking BIOS because I figured it was already enabled.
