My squad has vent also, but then you still have to use the AH vox to talk to non-squaddies. I would like to use an audio interface through a separate system, but after testing the device I am using now it does not appear to be a problem with AH3.
I was trying to eliminate the micro-pauses, but it seems to be a feature of DX11. Nothing I do on my system will get rid of them.
