Ah, no Audio is not disabled in BIOS and works fine in Windows..
Very Strange.
From reading some of the setup guides on here and other sites it seem Pre Mavericks it worked fine with the following drivers
VoodooHDA0.2.7.3
Several reports of those working but not on Mavericks it seems.
Just checked the Codecs on the Windows / PC Side Does this help
