I noticed when I went to AvA last night that my MIC stopped working.
I happened to just get into a ground vehicle when this happened.
From what I understand as soon as I started driving that ground vehicle, my controller mapping SWITCHED ITSELF to Mode 2 (Ground Vehicles) which I have never used or setup and knocked out my VOX which was mapped to my stick in Mode 1 (flying)
As soon as I went into controllers and went into Mode 2 and setup my mapped vox it worked fine.
