Same Problem.

Late 2010 MBP 4GB RAM; 500GB HD

same problem here late 2011 mbp with 10.10.2,

apple please fix...

I am having the same problem!

So last week we went to the genius bar to see what they'd say... At first he said that it clearly is a hardware problem and that they would have to put in a new logic board. Well... After i showed him that it was working for skype and photo booth he went to imovie and wanted to import video from camera and ofc the mac said no camera connected bc there was no external camera connected but he said the isight camera is broken bc he can't access it in imovie (that's not even possible btw) so enough said about their knowledge lol! After that he said it has to be a software problem caused by a third party app so a full reinstall has to be done and ff it's still not working after that it has to be a hardware problem. Luckily my gf didn't have a time machine backup so we just left without solving the problem. He even said they don't have one single entry in their database concerning the same problem and when i told him that there is a 20 page long thread on the forums he said that people talk a lot of crap on the internet and that all of those cases, if true, are caused by different problems. When we got home i hooked up an external drive, put mavericks on it and it was fine (well the audio drivers have been buggy since 10.7 but it was working). so i did some testing, had facetime run for 24 hours, no mic problems or clicking static noises whatsoever. after that i went to update it to yosemite and boom it was back to not working. Once the clicking noise was there it was there for good. Took me quite some time to get it working again and plug in headphones and unplug 'em and it's not working again.

When we left the store he said my gf should give it to them for testing to see if there is something wrong. If they can't find anything it's free, if they do she'd have to pay for it and i know those greedy suckers will find something to make some more money off that horrible problem they created... we took it back home, i'm gonna put a samsung 850 evo in there and install mavericks on it and call it a day. This whole thing is a huge disappointment. My worst genius bar experience ever. He wasn't even listening to what i was telling him and on top of that he was really rude

I can’t believe Apple! I brought up this issue over a month ago after installing Yosemite on my wives 13 inch Macbook Pro. Like many of you the problem never surfaced until the upgrade. Like Maxmw, I talked to Apple representatives in Seattle Washington and got the exact same response about how people “talk a lot of crap” on the internet about problems. I can say without reservations YOSEMITE OSX IS CRAP AND NOT WORTH THE AGGRAVATIONS! If you are thinking about upgrading DON”T. If you are still experiencing problems remove Yosemite and reinstall Maverick!  Apple is morphing into Windows by creating operating systems that are flawed. It is obvious Apple doesn’t give a **** about this issue. They see it as an opportunity to sell you a brand new computer. Another example of the bean counters running the technical department.

One more here, late 2011 macbook pro with 10.10.2,

making strange clicking sound since OS X 10.10

Apple please fix it

I have a MacBook Pro Mid 2010 with the same problem. I was afraid my computer was getting ready to crash or something. I hope Apple can fix it. I want to FaceTime with my grandson.

10.10.2 and 2.66 GHz Intel Core i7

I don’t think we should hold our collective breath on this issue! Maybe we should change our venue and post our complaints to the “Feed Back “ section of the Apple Website! I highly doubt anyone from the Apple Corporation reads this forum, how else can you explain the lack of response from Apple? Page after page of issues and still no remedies offered by the company! I don’t know how to get them to react to this situation. Many people like myself use FaceTime to keep in contact with loved ones and family all around the world. It is in some cases the lifeline that binds them together. I loved the cute commercials Apple produced  last Christmas showing families getting together sharing memories and events with loved ones. The reality is, if you have one of these affected computers they would all be standing around trying to hear the persons conversation! This is not acceptable from a very pricy machine! It is very obvious that this is a software problem since it only affects computers that recently been upgraded from Maverick or earlier to Yosemite!

The simplest temporary solution is to plug audio jack, and then unplug it. It works immediately for me without any restarts.

I got two OS X installed on my macbook pro (10.9 and 10.10), and on 10.9 everything works without any cracks.

I hope 10.10.3 update will fix the issue... still hope... hoped for 10.10.1, hoped for 10.10.2 and now hoping for 10.10.3

Update.

After nearly two weeks of discussing the issue with AppleCare, resulting from my complaint to the BBB, I've been told the issue--according to Apple's engineers--is faulty wiring between the speaker and logic board, presumably from a bad previous repair. The fact that the issue only crept up and exists with Yosemite is a moot point with them, they don't care, and I was told to get it repaired to fix the issue. Meanwhile, as of 10.10.2, the degradation of audio with this computer increased to such a point that I've resorted to running Windows 8.1 via Boot Camp full-time for the past three weeks (and counting) to get work done. Everything from Spotify to Skype to iTunes all work flawlessly under Windows 8.1 via Boot Camp with this MacBook Pro,

In sum, AppleCare has told me to "buy a new Mac," "wait for a possible software update," or "repair the computer for a likely wiring fault" (paraphrasing). I cannot "downgrade" to Mavericks because I am given an error message that prohibits me from doing so. I will have to dig and find the Snow Leopard disc that came with this computer if I want to regain OS X functionality but I think I'll stick with Windows 8.1 for the foreseeable future, especially since Apple has given little choice but to use Windows.

The sad reality is I should never have bought this infernal machine--it's been nothing but a piece of junk since I got it, and I can see the money I spent might better have been spent elsewhere.

Dear all, i had the same problem with 10.10.2

installed the older version of soudsource 2.5 here

now it works, it's a solution till apple resolves the issue.

P.S don't install ver2.5.1 cause it won't work with 10.10

But what's this soundsource?? How it works??

Thank you very much, that helped a lot, its working!

It is an application which lets you change inputs and outputs for your sounds, it opens on the top of your screen and looks like a headphone , right-click it and say open on log in

Ok but this is the same thing I can do with system preferences>sound, or not?? Wich is the difference? I don't understand...
