Does 7VTXE+ have SPDIF output?

Short version: Does the 7VTXE+ have SPDIF output?

Long version: The manual says nothing about it, but the onboard AC97 appears
to have some kind of SPDIF option: in the Windows Volume Control there is a
control labeled "SPDIF" with a grayed out volume bar and a "Mute" checkbox.
Changing the checkbox state seems to have no effect.. Or does it? Is there
an unmarker spdif-out jumper somewhere on the board? Or, is there some way
to turn the analog audio out into a digital output?

thanks..
