No sound from MacBook Pro

The sound on my Macbook Air just suddenly stopped working - there was no sound at all from the headphones or speakers (it was working just a few minutes before).

A simple restart of my laptop and everything was back to normal.

Not sure why though - I tried the solutions on here and they made no difference

I was able to use my bluetooth headset but not the internal speakers. After reading thru the suggestions posted here, I remembered that I had connected external speakers to listen to music. I went back to the external speakers, plugged them in and somewhat gently wiggled the input and pulled it out quickly several times until it reset the internal speakers. Beats me as to why this was a fix but thought I would share my experience to re-enforce similar fixes posted.

Hope this helps!

As above... after a new HD being fitted this fault was occuring on and off. Tried the headphone jack method and it cleared it up. For now...

Having the same problem, I tried to use the headphones and see what happens (updates didn't work for me).

After plugging them in and out a couple of times, sound came back!

I noticed a red light in the audio jack (I believe after the first time I took the headphones out), which switced off when speakers worked.

Having a similar problem. I have a MacBook Pro and the internal speakers work. However, if I plug in speakers or a headphone the sound stops. Unplug them and I get sound again. After reading a bunch of threads and trying the suggestions, which none worked, I saw a reply regarding that the problem might be Adobe Flash. Well, since I've had this laptop since September (bought it with Mavericks installed) and didn't have this issue until a couple of weeks ago (I always keep speakers plugged in and wake up my Mac and shut it down automatically each day), I thought that it must be something recent. Using Adobe Flash as a suspect, I looked in the Applications folder, but did not see it. Then I sorted the Application files on the date an found that Utilities was changed on March 14th. I opened it and found an Adobe Flash uninstall app. I uninstalled Adobe Flash and now the sound works again through the plugged in speakers.

So it seems more of an Adobe Flash problem, but shame on Apple for not posting something on this or working with Adobe to get it fixed. On that note, I've been using Apple computers since the 1980's and they were clearly better than the alternative during most of that time, but recently, Apple is making everything worse in my opinion. iTunes absolutely ***** now, the Mail program is subpar compared to Outlook, Finder is just passable, and Mavericks? What the **** is that? I havent' seen one new thing that is useful and taking away the arrows on the scrollbar? Apple could at least make it available via Preferences. The only genuine thing Apple has going for it is security. I think their programmers either need to work on entirely new things or get another job. The problem is they got things right years ago, such as with iTunes, and since they can't find enough work on something new they spend their time re-tweaking and making changes to exisiting apps just for something to do, and are making things worse. But the worse thing is the arrogance to force everyone to the latest 'de-improved' version. Take iTunes for instance. I tried to keep my iMac iTunes version when I migrated to the MacBook, but Apple rigged it so that only the latest iTunes version works with the app store. They better wake up or their recent fall from record heights is going to accelerate.

I had similar problems. I'm not sure if you've tried this, but I was getting a "forbidden" sign when I'd try to up my volume, and the internal speakers weren't even listed in the sound options. But, I plugged in headphones and got sound. When I unplugged them, plugged them back in, and reunplugged them a couple times, suddenly I had sound again. Hope this helps someone!

Props to OGELTHORPE -- worked a treat for me on Mavericks! 🙂

This worked for me too! THANK YOU! 😀

I also came upon this solution on my own a few months back for my MBPro but it's starting to get worse and worse- I now have to really mess with that blasted jack in order for the sound to return. Apple really has to work on a solution for this particularly poor piece of engineering.

I visited this discussion a few weeks back and tried some of the solutions. They worked with varying effectiveness. The most effective was to quickly whip out the headphone jack and 'fool' the computer into recognising the built-in speakers. But it just got worse and worse. Until today I plugged in a USB VoIP device (USB headphones with a microphone for Skype etc.). As soon as I plugged that in the internal speakers were recognised once more and I can select them from the menu as an option - and they work! Consistently. This is a software issue, not a hardware issue. Apple need to get their act together! Give us an update that solves this issue. I have already been told that the macbook pro I use needs to go in for a repair to the socket. It's simply not true!

Just recently discovered this: If you select the Output tab directly next to Sound Effects, you will find this:

Don't worry about anything except what you've selected. If you select Soundflower (2ch) and then select Internal Speakers, you will find that the sound works again.

P.S.: BoomDevice is something that I've downloaded separately and is not required or recommended for this to work.

P.P.S.: I discovered the Output tabs a long time ago, for anyone that thinks I'm an idiot.😝

Thanks Steven_Mobs,

That worked for me. After I upgraded to Yosemite, I had the same issue of no audio (audio indicator crossed out even after I increased volume on my keyboard). Yosemite seemed to have defaulted my Dell U2413 speakers instead of the built-in speakers. Changing default to built-in in the Output tab solved the problem.

My sound is like that so how can i fix the sound problem?

Before, Sound Preferences showed only one option, Digital Output, and the volume controls were disabled. After plugging headphones in, adjusting the volume, and unplugging them, Sound Prefs show Internal Speakers (Built-In) again and my Macbook Pro is back to normal.

WORKS FINE!!!

Help me very very very.

Thank You

That was my problem exactly- thank you. I thought maybe a part of my headphone plug must have come loose inside the laptop, but I tried your trick, and its working fine now. When I went to the sound control, it didn't have any internal speakers as an option until I tried this.
