no sound from my 003 rack

I am using Pro Tools 11.1.3 with Mac OSX 10.9.2. I recently upgraded to Mavericks and this is the first time that I am trying to use my 003 rack after that change. I just upgraded to the latest version of Pro Tools and installed the drivers. But now I cannot get the audio out to route through the 003--I continue to hear it only through my built in computer speakers. In Pro Tools/Setup/Hardware the only thing listed under "peripherals" is "Pro Tools Aggregate I/O" but my 003 rack shows up when I launch the setup application from the Hardware Setup screen. In the setup app I have the 003 rack to be used for sound output. Also under Apple/System Preferences/Sound I have the Avid 003 rack designated for sound output as well. Yet I still only hear it through my computer speakers.



Anyone have any ideas on why this is?
