My machine is MacBook Pro (Retina, 13-inch, Late 2013), OS 10.10.1 (14B25).
I just tried to make a voice call in Google Hangouts, and Hangouts does not pick up any sound.
I checked System Preferences -> Sound -> Internal Microphone, and the Input Level meter shows no activity - not when I talk, clap, or hit the case.
How do I fix this and get my internal microphone to register an input correctly?
System Preferences -> Dictation and Speech -> Dictation has an icon that says "Internal Microphone" and appears to register sound. In fact, it seems to be very sensitive.
Some things I have checked:
- Under Sound -> Internal Microphone, Input volume is turned all of the way up.
- I have no devices plugged into the headphone jack.
- In Audio MIDI Setup, I've checked that Built-in Microphone isn't muted.
- I shut down the computer and started it up again, and again while holding command-option-p-r (although I don't actually know what that does). It didn't help.
