I have a G4 with analog audio in (microphone/line).
I am desperatly trying to enable playthrough for the line in input.
According to apples Documentation, there are two functions:
AudioDeviceGetProperty and AudioDeviceSetProperty.
The Hardware of the machine supports playthrough, also there is a Software on the web called "playthrough FX" which actually does work.
But when I call
AudioDeviceGetProperty(deviceNum, true, kAudioPropertyPlayThru, NULL, &data);
always an error is returned.
The device Number is "10", that should be the "Built in Audio Controller" of the G4.
Is there any sample code which demonstrates this feature?
Also, do I have to switch between the micro an the line input? If yes, I dont know how.
Any Ideas welcome
thanks
