I found a descriptions of that board at 

The feature list says what you posted, plus the following:

Audio Subsystem
• With external high quality 5.1-Channel AC'97 Codec
• Complete software driver supports for Windows OS
• Optional SPDIF out function

On board connector for external device
• Optional 3x2 pin SPDIF connector for additional SPDIF-out adaptor

If your board has that header, you would only need the connector, and 
you wouldn't be using the (analog portion) on board audio.

You'd just need to determine if the linux driver supports pass through 
with that audio chip, and what the adapter costs compared to a 
replacement audio card.
