I have an application which will only take audio from the microphone input to send out to a chatroom. The PC version of this app will take sound from the sound card as well as the microphone input. On the Mac, this is not the case; there is only one source for audio, that is, the microphone. Is it possible to redirect audio from an audio producing application and connect loop/wrap/connect that audio to the microphone input only chat room application? That is, without soldering up a wired connection.
