Sorry, it's been insane here at work, so I haven't had a change to play with my carputer for a while. Anyway, I was playing with the latest build you sent me. With my carputer (a laptop) out of the car plugged in with a normal microphone, the program works great. However, when I put it in the docking station in my car and use the hotkey with my iBus control and use a USB Microphone... the system doesn't work at all. Sorry, I haven't had a chance to really get into it, but when I use my iBus connection to pass the F10 key it turns the mic off and on.
I'll try to get some more details this afternoon.
