i am using apple iphone headphone.

I am using a new mac. I just installed the latest update.

currently, i tried to plugin the iphone headphone, it works. but the volume control button on the earphone doesn't work.

i pull out and plug in the headphone again. the sound will come out from my speaker. it seems like mac didn't detect any headphone.

I have tried to restart. it will work for the first plugin. after that it will not work again.

I also have tried reset the PRAM.

Same thing.. first time headphone work without volume control over the headphone. after i re-plugin. sound will only come from speaker.

Hope to hear from you soon so that my new MBA can work.

Hello!

I know this is an old thread but I have just experienced a similar issue on my MacBook Pro mid-2010 running on Mavericks 10.10.2. Here's the thing: my mid-2010 MacBook doesn't support AirPlay, but I have an Apple TV, so I had to download a software called AirParrot, which allows me to use AirPlay.

I just found out that when I plugged my headphones in, the audio output would actually switch to AirParrot instead of "headphones" (I saw this in System Preferences > Sound). I then manually set it back to "headphones", and voilà!

This is a really quick answer, but I hope it can help!!

Start your own thread. Your issue is not similar to the OP's issue.

If for no other reason, you wouldn't be able to award points to those that may be able to help you, because only the original poster can do that. Thus eliminating an incentive for people to help you.

Thank you so much, this fixed my audio.

Thank you thank you thank you, I had no idea how I was going to get my jack working for my great sony speakers, but your help was the first thing I went to and saved me a big headache, I appreciate people that go out of their way to help others with technology issues.

Much Appreciated,

Using the Audio MIDI Setup helped me fix the problem. Another device (Epson Projector) had somehow reset my audio settings. Audio MIDI Setup worked to re-establish the headphone output.

Thank you mikehammon! This solved the problem for me as well. You would think Apple could design a port that could automatically recognize this, or at least pop up with a dialogue to ask what you want (input or output) as opposed to having to use a frustratingly obscure setting, wouldn't you?

I had a similar problem and I solved it by just making sure than in the System Preferences / Sound the Output menu (blue button between Sound Effects and Input) with Internal Speakers (built-in) highlighted has Sound Output selected in the "Use audio port for:". Now, when you plug in your headphones it should recognise them. After installing some audio sampling software on my MacBook, this option mysteriously changed into Sound Input which stopped headphones jack from being activated.

I hope it helps.

So it's not just in space no-one can hear you scream.Looks like a bit of bad release code, with varying effects and a few solutions.

For me - with neither headphones or external speakers able to work from the jack, but the sound fine from the built-ins - the answer was in...

System preferences/Sound/Output: I found the Output Volume 'mute' button was ticked - presumably switched during the upgrade. Untick and... headphones and speakers back to life!

Hope this helps someone out there.

Thanks LT.

I am newer to Apple computers, I have a Mac, so I can't tell you the OS version. I know I have the most recent as of 1/14/16. I have had this problem for the past 3 months and just ignored it until I needed to use Skype w/ headphones. I used your solution, but had to deviate to get the same results. I followed your directions via applications to get into Audio devices, HOWEVER my left window showed Microsoft's "logMeIn Remote Sound" as well. Changing the 2ch-32bit integer didn't work. But after right-clicking on Built-In Output and clicked Use this device for sound output (with the headphones plugged in). The headphones started working! I came to this conclusion because when I had Audio Devices open and plugged in the headphones and saw the head phone emblem switch from Built-In to LogMeIn. Showing me that somehow Microsoft assumed default. So I changed that and bam, there was sound in my ears. I appreciate you help. I hope this helps anyone else with Mac/audio issues after the upgrade.

Thank you this worked but there was one more step, I had to back to the sound settings and click on the headphone setting and voila sound.

Thank you so much this worked for me

For my MacBook Air, Late 2010, the problem occurred after I had installed AirParrot. Sound output was then auto directed to that. Fix was to change the output to Headphones from System Preferences > Sound > Output. Restart (at least with no headphones plugged in) did not solve the problem.
