VOXATC P3D Problem/Annoyance

Hi All,

I'm using VoxATC v6. After Atis, Clearnance,and Ground. when given taxi instructions all of a sudden I get audio that sounds like another prop aircraft. It's very loud and annoying but there are no other aircraft near me.

This only occurs while using Vox. Doesn't matter what aircraft I use. I can even shut down my aircraft engine and I still hear a phantom aircraft.

Any ideas? I've posted this in VoxATC forum as well.
