Default PT Not Reading Mic Signal on MOTU 8Pre USB

Hi guys,

I added a new secondary (slave) preamp unit to my DAW yesterday but when I went for a mic test Iím not getting signal in PT, even though Iím seeing signal readings on both the unit itself, as well as within the virtual mixer software.

Here are my setup specs:

Iím on PT 12.5 on Mac laptop OS 10.11.6
Main audio interface is MOTU 828 mkiii
Slave preamp unit is MOTU 8Pre USB (the newer usb version, not the older FireWire version)

I have the two Motu units connected via ADAT expansion, with the 8Pre as slave unit.

PT is not recognizing mic pre input via ADAT expansion. It recognizes the primary interfaceís (828 mkiii) line level, but not the slaveís line level.

All settings changed appropriately on computer. Aggregate set to same bit depth. Sample rate 44100. Using master as clock.

To be clear, we are seeing signal readings on the interface and on the virtual mixer software (Cue FX) but PT is not reading level. This makes me think that it could be some PT setting that needs adjusting? Or is there a compatibility issue with the 8Pre and the Mac OS version Iím using? Not sure.

If anyone has ideas on what to try Iíd appreciate it. Thanks!
