No output audio on MBP Retina, only startup chime

My MBP Retina 13" 2014 A1502 has no audio output device. Only on startup do I get the start up chime, then I have no output from loudspeakers as well as from the headphones jack.

What I've tried so far:

  • Reset NVRAM, SMC reset
  • Format and Reinstall of OS X El Capitan 10.11
  • Create new admin user
  • Startup from Safe mode
  • Apple diagnostics show no error

When sending audio via bluetooth to a wireless speaker works fine, so I think the soundboard is OK. Also the systems loudspeakers seems to be OK, as I can hear the startup chime.

Any idea?

Thanks!

If there is no red light inside your headphone jack, I would check System Preferences / Sounds / Output to make sure Internal Speakers are selected.

If there is a red light inside your headphone jack, it means your Mac thinks an audio plug is inserted.

I've read of people wiggling a headphone plug or a toothpick inside to reset the internal switch.

If the switch itself is damaged, the audio port integrated into the main logic board; and the whole board would need to be replaced. It's an expensive repair. Pro 13" Retina Display Mid 2014 Logic Board Replacement

Good luck.

I have no Output Device to choose on that list. What red light do you mean?

he is talking about a red light from inside your headphone jack

Yes, sorry I wasn't more specific. If you look into the port you usually plug-in headphones or speakers, there is a red LED that will light up if the hardware thinks a plug is inserted.
