Winlink Express & KX2 with DigiRig

I have WInlink Express running well on my KX2 with the DigiRig. Contacts are good. Running with 5 watts RF.
However when I try to adjust the ALC there is no ALC shown on the scale, so I set the MIC setting to around 50 which I used with my previous digitial interface. ALC is shown when using the microphone.
Any suggestions as to how to get my ALC back with DigiRig ?
