There is some confusion here. I think it is important to note which version/year you have. Some of the earlier versions have the option of selecting your audio output. In my case (2011 macbook pro) that option is run automatically when you plug your headphone in. I have to reset the laptop with the headphones plugged in for the output to switch to 'Headphones'. There might be some root priviledge that is required to do the switch and the problem may be a conflict between the logged in user password and the root password. Make sure they are the same and reset your PRAM/NVRAM.

And 3000 for Business appears to be a Windows only webcam. In either case, that is the likely reason the webcam's mic is not working; they're not compatible with OSX.and if i plug in a headset it wont work ether. Are you referring to a microphone attached to a headset? If so, then as I mentioned, the Mini's audio in is NOT a microphone input. FIX YOUR WINDOWS 10 AND ANY WINDOWS PC PROBLEM. I got having trouble lately when I am trying to connect my head phones to my computer. So I go to the internet I search for every possible solution.

That seems to have fixed the issue in my case. Again, this is only for the case where you have no option in the sound utilities panel to select Audio output. Further proof this is not a hardware issue. I fixed the problem. I found a solution on one of the MANY discussions about the headphone jack failing after a Lion upgrade.

Under Sys Pref> Sound >Best mac software for editing voice audio. Click on Internal speakers. Then at the bottom set audio port for 'sound output.'

And here is the original post w/ that solution: That simple. I wonder why the 'Geniuses' refused to check my sound/audio options. I guess they were so brilliantly trained to blame everything on hardware instead of saying 'I dont know, let me do some research for you.' My headphones aren't working either! I contacted Apple Support and they insisted it was a hardware issue - and it's SUPER FRUSTRATING because this only happened after I upgraded to Lion.

I've searched online and several others have this problem - some have fixed it by changing their output to 32-bit Float in the Audio MIDI Setup. But that solution does not work for me. Does ANYONE have a clue?

Apple Support wants me to pay to have my computer shipped off somewhere and 'fix' my hardware when that's NOT THE ISSUE. This is so frustrating. I'm beginning to hate Apple, and their 'geniuses.' I should have never updgraded 😟. As a student who studies in the library, headphones are crucial!

And now I'm SOL because Apple refuses to acknowledge they have a serious software issue. Yes, tried all those steps.

I've talked to apple support online. Apple 'geniuses' refuse to acknowledge that this is a Lion issue. Yet, there are SEVERAL posts on this website alone that have audio issues after a Lion upgrade. Basically my solutions, according to Apple 'geniuses,' are: 1. Pay $$$ to get hardware fixed. Be without a computer for two weeks. (Even though it's not a hardware issue).

Revert back to Snow Leopard. Spend time removing all your files and apps off your computer, and then spend hours putting everything back. I have to choose option two, I guess.

I'm not going to pay for something that is NOT A HARDWARE issue. And since I have to revert back to Snow Leopard, I asked Apple for a refund on Lion. I'm going to have to deal with this after my finals.

I'll let you people know what the outcome was. I'm seriously, seriously upset with Apple refusing to acknowledge they put out a faulty product.

It's really upsetting. It's even more upsetting because they pretend to be the 'good' guys of the computer world. And really, they're just like everyone else.
