Internal Mic not working on MacBook

[rprince]

All I want to do is use my skype so I can talk to my close friends who have moved to the other side of the world - I'm fed up of wrting on sticky pads and holding my messages up to the screen so they can see what I am saying.

I think you might have been joking, but in case you weren't, you know you can type to send messages to people in Skype?

opening up speech and dictation fixed it somehow?

Hi! I made an account because I had what sounds like the same problem and somehow either updating to the latest software (yosemite as of now) and/or opening up dictation and speech has fixed it for now. I have no idea why. But if anyone else has this problem you might as well try it if you haven't already.

I was on skype with a friend, hung up, went to go do something else without moving my laptop at all, and then when I tried calling him again when I got back he couldn't hear me at all. I went to sound under settings first and it couldn't pick up my voice at all even though input volume was on full blast, but it could pick up if i tapped the mic with my finger. So I looked around the internet and did an smc restart, messed with terminal, messed with audio midi setup, made sure nothing was on mute. I didn't have any other mics to select other than the default so I couldn't switch that around. Finally I decided to try the free upgrade to yosemite. At first it still didn't work but then I randomly opened up speech and dictation under settings and it was all working perfectly again and I could talk on skype. BUT when I opened up sound prefs again it stopped working. Opened up speech and it was working again. Perhaps somehow those two panels turn something off and on? Very strange. Anyway I hope this isn't too incoherent as my coffee still hasn't kicked in yet but I hope this helps someone and maybe someone knows why this could work.

Possible solution

Hey, I had the same problem... and surfing trough here and there found my solution: Go to Utilities>Audio MIDI Setup and check if the mic has the "mute" checkbox... well checked. If you uncheck it... you'll instantly recover your mic!

Hopefully it works for you too.

This thread is super old but I registered to the forums to say a huge THANK YOU for posting this solution! I thought my internal mic was broken or something but you just saved my life. Thanks
