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.
