No "Internal Speakers" option (sound only works in Bootcamp)

Hey there,

I bought a "new" 2016 13" MBP (Non Touch) a few days ago, and everything was fine. But now, the audio suddenly stopped working in MacOS, there's no 'internal speakers' in the system preferences.

The weird thing is however, my sound does work when I boot into windows 10 in bootcamp.

Plugging in headphones, and the sound works, but removing them had no effect.

I'm running the new MacOS 10.14 Mojave beta, could it have anything to do with that?

I wouldn't suspect a hardware fault as the MBP is practically new and it works in windows....

Resetting SMC does make the charging sound audible, and in Windows it detects that the headphones aren't plugged in. However, in MacOS only the 'headphones' option is visible.

Tried plugging in headphones a few times and unplugging them, didn't work. Reinstalling MacOS 10.13 and 10.14 didn't work either.

Since you just bought the system I would visit the Apple Store to see what they say. You could also post a message in the Beta bug report as well.

I bought this laptop second-hand 'new'. I have the receipt, but it's just out of warranty. It was bought in Jan of 2017... So that isn't really an option. Or would they help me for free? There's also not an apple store closeby, so I want to be sure I can be helped... It must be possible to force the sound over the speakers instead of the headphones, mustn't it?

The headphone jack has a switch within it to send the signals to the speaker. It sounds like your jack is bad but given the fact you just updated the OS its also possible the OS driver could be messed up.

I would still go to the Apple Store, it won't cost you anything just letting them take a look. It might be still covered under warranty as Apple allows transfer of the coverage.

I know for sure it's not the OS now, I just downgraded to high Sierra and everything was fine today. Now I open my MacBook after moving it around some, and it's again stuck on the 'headphones' mode. Yesterday, it fixed itself so I hope it will again. When I'm close by an Apple Store I will ask them for some support.
