MacBook Pro won't pick up microphone, other audio applications will, what's the prob?

[ashinyjade]

I opened up Photo Booth to record a video for YouTube today and realized that I had recorded my self for 7 minutes for almost no reason.

Photo Booth doesn't seem to be detecting my microphone at all, because when I play the clip i recorded, there is no sound. My speakers are on, trust me.

Also, other audio recording applications, such as Screenflow and Audacity are able to pick up the microphone easily.

I've ran the application with nothing else running and get the same result.

Does anyone have a solution?

Thanks in advance.

A good starting place would be:

System Preferences > Sound > Input, then highlight "Internal Microphone"

The other apps probably are using their own selection of input devices, rather than the system default.

You sir are a genius.

It had "Soundflower 2ch" selected as my default. There was also a "Soundflower 16ch" selection as well.

What could those be?

Perhaps it's part of some piece of USB audio equipment interface that has inputs. I have a M-Audio Fasttrack Pro which has both outputs and inputs (as a for instance).

External mic

Do you have any tips for me, I want to use my external microphone but my mac isn't picking it up in the system preferences or in any of the programs on it!

@sobie: You'll need a FireWire or USB audio interface to act as a pre-amp in order to use an analog mic; alternatively, a USB microphone will do fine. There are no FireWire microphones as far as I know. If you are using a USB microphone, check in Sound preferences->Input and see if it's recognized.

Alright.... who changed my settings?!?! Thank you SO much! I was afraid my 2012 Macbook Pro was dunzo. It's back alive!

This problem with USB microphones was fixed with yesterdays release of MacOS 10.12.5
