Good day all.In order to send the ATC through a headset, I installed a Plantronics USB headset to my W7-64 Pro FSX SP2 system.I have the speakers setup for FSX output and I have V6.05 pointed at the headset.Testing VoxATC via the Voice Config page confirms that the sound is in the headset only.Testing the Voice Rec via the W7-64 Control Panl confirms that the Mic is OK.Running FSX confirms that the engine sounds are through the speakers only (audio is connected to the on-board Realtek sound).Initializing V6.05 starts off OK with each voice Testing correctly (I can hear them).After the voices test, the Initializing dots (.....) stop and nothing happens.When I disable VoxATC and unplug the USB headset, and re-initialze, it starts normally and seems happy.I've tried various combinations but the result is the same.It seems that the USB (ie. 2nd sound card) makes VoxATC unhappy.Can anyone shed some light here?ThanksNick

Hi Nick,I think you will have to contact the developers for this: http://voxatc.com/Contact.aspx Helge
