Audio not working, MacBook Pro 13" with touchbar

Hi,

Recently my volume has stopped working on my new MacBook with touchbar, other than that it works perfectly. Whenever I try plugging headphone in too listen it still doesn't play audio. Just wondering if anyone else has had this problem or if anyone knows how to fix it.

Thanks, Sam

I'm having the same issue. I have to restart the computer to get the audio back – very frustrating.

yes very frustrating. Hopefully its just a bug and it will be patched in the next OS update

Have you tried opening System Preferences-->Sound-->Output Tab?  Make sure that your headphones are selected and that audio isn't muted. Hope that helps.

This isn't the issue. Audio is enabled (both internal and headphones) in prefs. I do hear a slight 'click' over the headphones when plugging them in but other than that there's NO audio playing. The last time this happened it came back with a reboot, but this is obviously far from ideal.

Still happening to me on macOS Sierra 10.12.3.

A reboot fixes it, but when will Apple.  The next time it happens, and I have time, I'll call AppleCare.

I am having the same issue with my MacBook Pro 13" Touchbar. The audio just randomly stops working and I have to restart the computer. Whenever this problem occurs the headphones don't work and internal speakers don't work either. I've checked and the volume is turned up on the computer as well as on iTunes or on YouTube videos, so I should be getting sound. I've checked the "Sound" settings in System Preferences and everything is set correct. The output device is set for internal speakers. I've called Apple Care several times and they've had me reset my SMC and reboot the computer and that fixes it, but we've not discovered what is causing this issue. I've had this computer less than 5 days.

I have had the exact same problem on my 4 day old MBP 13" with touchbar. I think it has something to do with Flash. Sounds works fine when you turn it off.  I had to turn it on for a streaming service...... sound went dead. Reboot didn't work so I tried Flash and all is well.

Same problem with Macbook Pro 15" 2016 with touch bar. It happens after the computer went to sleep, when it wakes up the sound is not working. First time with these kinds of problems since my first PowerBook G4, I believe that this it what happens when you don´t have anymore a dedicated MacOS team . . .

Btw, the sad solution is to open a console (Terminal.app) and kill the coreaudiod daemon:

sudo killall coreaudiod

I had this issue too - Macbook 2016, 13" with touchbar, OSX 10.12.6.

No sound through either headphones or internal speakers. "No output device" listed in System Preferences > Sound > Output.

Tried a bunch of things, including

- restart computer

- restart in safe mode

- killall coreaudiod && killall ControlStrip

Resetting NVRAM worked for me (see here).

It's August 2017 and I see this issue still happens. My four day old MacBook Pro 13" with touch bar is doing this and it's giving me fits. And sorry, but we shouldn't have to zap PRAM or NVRAM on a four day old computer, or restart it multiple times to get sound to work! This is basic functionality!!
