Does anyone else have this issue where the audio/sound stops working on their new 2016 MacBook Pro until it's rebooted?

I've checked the audio output device to ensure that the right one is selected, nothing is occupying the headphone jack, it's not sending via airplay, and neither the app(s) nor the MBP are muted. The volume icon still shows as if it's supposed to be working, but there's just no sound. Plugging in headphones or changing to another output device doesn't help either.

This seems to be happening on the laptop waking from sleep, though I'm not certain.

that happened to me once. I ran a command to kill the core audio process, but I don't have the command on hand. Once the process was killed, it was re-spawned and I had audio again, but the volume buttons didn't work.

I have the same problem, usually after the MacBook was asleep for a couple of hours. No headphones that I try have sound. I have not found a solution yet (besides a reboot, which is very annoying).

Any ideas?

I've been hitting this bug a few times recently on a 2016 rMBP, where the audio output from the internal speakers stops working completely after it's been asleep. Output over BT devices like AirPods works, but the internal speakers don't. Thankfully, the Terminal command mentioned by neil218 works a treat to fix the issue without needing to reboot! Now Apple just has to fix the bug...

Happened to me yesterday, I tried to play some music through iTunes but couldn't hear anything so ended up restarting and it worked after that.
