So I ended up figuring it out. For some unknown reason ( I don't recall having done this myself, but ah well, damn you whiskey). The SM Digidesign card was muted in the system settings

To change this on mac OS 9 (it took me a second to find it as I'm not on this machine as much as I would like)
1. Click the apple icon in the top left
2. SCroll to Control Panels
3. Select Sound from the expanded out submenu
4. Confirm that the main volume isn't muted and you should be good to go.

Hope this helps.
