Firewire 800 to audio out - XSERVE 3,1 - need L/R stereo outputs

[4sallypat]

I have an XSERVE 3,1 running Yosemite OS X and would like to have audio output from the Firewire 800 port.

Is there an adapter or module that can output audio (2 channel) from the XSERVE thru it's built in FW800 port ?

I have run out of USB ports and since I have 1 unused FW800 port, I thought I would ask the gurus here...

There are firewire audio interfaces. Look at Presonus fiestudio mobile or a focusrite saffire.
