MacBook Pro (2016) audio problem

I just figured out part of my problem. This isn't the complete answer, but I feel sort of stupid for not thinking about it sooner. I'm a teacher. I'm connecting to a projector by using Airplay to an Apple TV (previous gen.) which is connected directly to the projector. This is a new setup for me since getting the new Mac. I plugged my old Mac in directly to the projector. I just noticed that the projector is off, so I'm not hearing audio because the Mac is still connected to the Apple TV via Airplay. When I disconnected Airplay, the audio came right back.

However, I've also had this issue at home where there is no Apple TV. I wonder if the computer still thought it was connected since I had just gotten home from school when it didn't work?

Yes. My internal audio is sometimes dead, but most times I can use my connected 2nd monitor which has also audio speakers. Then the audio output is coming from there. A change back to internal audio is then not possible until reboot.

I'm also having this issue. It was fine for the first couple of weeks, but for the past few days, whenever I use headphones, the audio completely dies afterwards. Even after replugging the headphones, nothing. The only remedy is to restart – which is a pain!

Same problem, 13" Pro with touchbar. For me, sound works when pushing the touchbar for siri, but not for any other sounds or even the siri voice response, just the initial "beep". Restart fixes the problem temporarily. How do we get Apple's attention to this issue?

This doesn't seem to be a widespread problem. Lets try to find common denominator. Did you guys restore a previous Macbook or are using the new Macbook 2016 as a new setup. What version of OS X did your restore from.

In my case I restored from a Mid 2012 Retina Macbook Pro 15" running Yosemite.

I also have this issue as you all have described. Is there a way to vote on this fix? It is a maddening little issue.

This worked for me.

I've had this problem as well.

Resetting coreaudiod fixes the problem, but it's annoying seeing as how much I paid for a 'premium product'.

Apple needs to fix this!

The exact same thing is happening to my wife's 2016 MacBook. She normally keeps the audio muted but when unmuted no sound comes out of the speakers.

Rebooting the computer fixes it.

Happened for the first time today. 15" 2016 MBP TB a few weeks old. While I was reading the thread an email came in, speakers dinged and then sound was fine. No reboot or other changes.

My problem is that the computer emits a strange sound after restarting it does not work the audio several reboots it works

As apple will solve this problem?
