As other users before me, I have the problem of getting a microphone to work on a Mac Mini.
See for example:
Getting a microphone to work on a Mac Mini
One suggested option was the use of a USB device like iMic Griffin.
Now, I have an iMic Griffin, and I am pretty sure that everything is plugged in correctly and that the setup is fine, because the audio of my headset works fine and the blue bars on the sound property site visually react to sound from the microphone.
But when I try to use the mic with Skype, it doesn't work. (It is unlikely that Skype or the headset are at fault, because they work together on another computer.)
Do you have suggestions where the problem might lie? I would also be happy if you point out another Mac program that can be used to test the microphone.
