I have a laptop that's two weeks old. I plugged in my headphones for the first time today, and I had no audio, so I unplugged them and I still had no audio.

I have done the following:

  • Restart
  • Sleep
  • Shutdown
  • Plugged in headphones multiple times and turned
  • Checked for foreign objects
  • Reset PRAM and SMC
  • Restored from recovery console
  • Erased disc and restored new OSX from recovery console
  • Checked audio settings to make sure internal speaker, mute and volume and all ok.
  • Checked for light emitting from headphone jack
  • Checked that the micro switches in the jack are no depressed.

I am looking for more suggestions. I use the laptop for work everyday, so I can't afford to give it to Apple to fix at the moment.

It was a faulty logic board. Had it replaced under warranty and issue resolved.
