Q: built in internal microphone and meter not working
I have a 2011 27 in IMAC ; OS X EL Capitan Version 10.11.3; Processor 2.7 Ghz IntelCore i5; Memory, 16 GB 1333 Mhz DDR3
When attempting to talk to (dictate) my computer and/or use the audio/video apps for phone calls, and/or shooting videos, I cannot be heard by the person I am speaking with. I am able to hear and see the person with whom I am attempting to speak. Subsequently I have checked System Preferences>Sound> Built In Internal Microphone> Settings and discovered the Microphone is not working. The Input volume level meter is not working either. I don't know if this is a software or hardware problem. Please help1
iMac (27-inch Mid 2011), OS X El Capitan (10.11.3)

Try a Hardware Test: Using Apple Hardware Test - Apple Support
(I don't know if the microphone is tested during the test)
