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

Your 2011 iMac has two separate 3.5mm audio ports, one for Headphones and one for Line-in.


Headsets that have a single 3.5mm jack are made for newer systems that only have a single audio in/out port. They will not work with the older Mac's that have separate Headphone and Line-in ports.
