I'm putting together a system using an Asus K8-V-X motherboard. It has a
S/PDIF out jack. The manual says:
"This jack connects to external usdio output devices."
It looks like an RCA jack to me. I couldn't find much doing a google
search. All I got was retailers selling boards with the jack.

It has integrated audio on board with mini jacks.

So what's the additional RCA jack for? Thanks,

It is an RCA jack and is, as it says, for S/PDIF: Sony/Philips Digital
Interface.

It allows the transfer of audio from one device to another without the
conversion to and from an analog format.
