Mac sound stopped working headphones

This will also depend on what your hardware is. You'll need to type your admin password. Audio will stop for a second then the process will restart. I suggest you move on to resetting PRAM, as per the article, if this doesn't help. This is a very important article for every OS X user, thank you for this. My problem was no sound after unplugging headphones, sleeping iMac, then returning hours later.

Although the sound bar was adjustable and not muted in preferences, no sound was to be heard, headphones in, or headphones out. Glad this article could help you out! I'm really glad El Capitan suffers from these audio problems a lot less than Mavericks did, but it's definitely handy to know how to restart Core Audio when things start sounding weird.

Was enjoying watching using VLC and suddenly the audio was distorted for the speaking part but the background laughter, music was fine.. Really weird.. The mouse connected easily but I could never get the keyboard to connect, no matter what I tried. When doing a Google search I even tried some specific examples in the Apple support forum for this particular device. Once I tried this it worked like a charm. My macbook is also slow. My macbook says it's on mute and wont play music, please fix!! There's not much I can really suggest with such a vague description. Assuming you've tried everything here, you might want to backup with Time Machine and reinstall OS X.

If it's a software issue, that should fix it. It should also make things run a little faster too. How to backup and restore: Does anyone know how to delay audio output? I have managed to get all audio air playing through my sonos yes it took a lot of work but there is always a 4 second delay. I know you can delay certain apps like VLC player but can you just delay all output so you don't have to do it for each app?

I'm starting to think you can't but it seems like such a simple feature. Thanks in advance for any help. I use a headphone and speaker with my iMac. Today on a call, my internal microphone was on, how can I resolve that? You'll need to connect your headset in order for it to show up. My issue is with the Sound Preferences. I use an external device, i. This works. My question is 'why do I have to do this every time I turn the computer on? I'm having a similar problem with my iPhone contacts.

I select iPhone contacts only I don't want to scroll down my entire list of contacts looking for a number to call , but then after my next charge it goes back to all contacts. Its not a big deal, just annoying. I generally find that my Mac remembers the settings, based on the device I have connected. Are you running El Capitan? If not I'd suggest updating your Mac so it's as up to date as possible, you may also want to submit feedback to Apple: Thanks for the post!

Sep 2, 3: I have tried a couple of regular headphones and none of them will be recognized. However, there is no problem when i use the iphone headphones or iBeats.

The best thing to do in that instance is to uninstall the app. To do that, you should use a dedicated uninstaller like CleanMyMac X. You can download CleanMyMac for free here. The most common occurrence of this problem is on pre Macs that had a digital audio output support in the headphone jack. On those Macs, there was a sensor in the port that detected whether a headphone jack or a digital audio device was plugged in.

The Mac would then change the output to headphones or digital output accordingly. However, sometimes the sensor failed to recognise when a digital audio device had been unplugged and so the audio output remained locked on digital output, with no way to change it. With no digital audio output connected, there is no way to change the volume or hear sound. The solution in that case is to plug the cable back in to the socket and remove it again.
