This just started happening recently. When I plug my headphones in, I get full high fidelity volume for a fraction of a second and then it becomes significantly muted.

I've checked "Sound" in Preferences to ensure that I've not reduced my system volume.

Any other ideas on what might be causing this?


  • Tried restarting (multiple times)
  • Tried resetting NVRAM to no avail

System Specs: MBP 15" Mid-2014 on Yosemite

  • nope, not yet, please let me know if you did! – K - Feb 15 '16 at 4:16

I waited a couple of days and randomly I tried playing a video and the sound worked perfectly fine. I would just try waiting a couple of days like I did.
