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.
