[coreboot] What is the KGPE-D16 PCI audio device for?

[Taiidan at gmx.com]

I notice the kgpe-d16 has an AMD PCI audio device, but I am curious as 
to what the purpose of that PCI device is - the weird MIO audio card 
that ASUS sells appears to have its own realtek chip so I don't think it 
is that.

Is there some kind of header on the board that I am not noticing? does 
anyone know how to use the boards audio? or should I just remove it to 
save on MMIO space.
