GoFlight com not responding in P3D

I have P3D 2.6 and a Go Flight GF-46 (a/p, com, nav) and a GF-155A (com) with other GF buttons and switch modules as well as their throttle quadrant.  When I am flying the Flight 1 C208, I cannot seem to control the com, but other buttons , switches and throttles with my other GF modules work ok.  I could of sworn it was working before, but I had been on vacation and I kind of lost all memories of what worked and did not...  Any hints?
