Cannot get digital audio output from my Box 2 Mini. But can still hear the inputs (mic, line). I can get session audio to come through the built in Mac output, but I don’t want it to, I want it be like I had it before. Green light is lit on the MBox 2 mini, and midi works fine too. In my test session, I have “Main Out L/R” activated and not “Built In Output”.

When I’m playing session, I get no audio at all save for an occasional “pop” once in a while. I can bounce a test file and then hear it through the Mac’s inbuilt audio output, and audio in/out in Mac’s system preferences are set to internal in/out.

Running Pro Tools 10.3.8 on an iMac running 10.9.1 (although this problem was still occurring prior to updating booth Pro Tools and Mac OS).

Installed latest Avid MBox 2 mini driver 10.3.3 and tried to follow as many of the manual uninstall directions as I could.

In Pro Tools, I have tried different combinations. In Setup>Hardware, do I use MBox2 or ProTools I/O Aggregate? In Setup>Playback Engine, do I use MBox2 or ProTools I/O Aggregate? In Setup>I/O, do I use MBox2 or ProTools I/O Aggregate?

Using the MidiAudio Setup utility, which do I use? MBox2 or ProTools I/O Aggregate? Any time I select either, the volume controls are greyed out.

Can anyone suggest anything please? Hair tearing here.
