Pre-cueing on controller not available (Stanton DJC.4 Mac) (but it used to be)

I used to be able to use my Stanton DJC.4 controller perfectly and it was recognized as an audio output device and I could precue with it. After the latest update it is no longer recognized as an audio output and I cannot use it to precue anymore. It however does still recognize it as a microphone input stil lfor some reason.

Any help would be appreciated.
