Line - In mic doesn't work
hi, I have a 2011 iMac
And I have a headset with an included microphone, but when I go to System Preferences - Sound - Input. I see that when I select Line In, not the internal microphone, shows nothing in Input level. Like it isn't capturing any sound. How can i see if the microphone is damaged or is it my computer?
please help me
