Soundtrack Pro DSR11 Firewire Out

I'm not sure when this changed, but I can no longer send audio out of STP to the DSR11.

I have audio out when using FCP
I have verified all of the connections
I've checked that it is sending surround (as per Apple Doc)
Repaired Permissions
Reset PRAM

If I remember correctly, the DSR11 used to show up under System Preferences as an audio device... but I may be mistaken.

Any ideas?
