Hello,
I have just installed debut but I can't activate the microphone because the option is disabled (greyed). Of course, I have a microphone (it is integrated in my laptop) and it is working properly with other applications. The microphone wasn't used by other app when I was trying to use it with Debut.
Windows 10 64 bits, Debut v6.47
Microphone controller: Synaptics audio v9.0.285.10
Thanks
