Motherboard Audio?

[Purplehazeffc]

I've done a bit of googling & couldn't find what I was after.

SPDIF optical out on a motherboard.

Does that go through the onboard codec like a Realtek 1150?

Or only though the 3.5mm audio jacks.

I'm after a new motherboard & will be putting the audio out via SPDIF to my Yamaha theater amp.

Which has a built in DAC of course.

A cpl of boards I've found have the lower Realtek Codec, but with the features I want.

Also a cpl of boards that have the Realtek 1150, but cost from $40-50 more.

Cheers.
