Tried rebooting my Mac and it won't help.
Running a Mid 2012 15" MBP (Retina).
Take a look at this : https://discussions.apple.com/thread/4841428?tstart=0
Opened sound in System Preferences and saw this.
The thing is though, I've never used headphones.
Do you see the red light in the audio port ?
Apply this (from the previous link) :
"Look in the audio output port.
If you see a red light, then the internal switch is stuck. Insert the phone jack a few times and see if that will trip the switch. If no success, try a cocktail stirrer or the like and jiggle it inside. If still no success, bring it to an Apple store.
If there is no red light, try a PRAM reset:
There was a red light before, but now it's gone.
A PRAM reset didn't fix it.
You might :
- repair the permissions in Disk Utility
- shut down the computer
- reset the SMC
Il the problem is still here (with no red light in the audio port), try the Terminal as suggested in the link.
Didn't try repairing permissions yet. I'll try this and report back.
Nope, I'll be trying Terminal next.
Edit: It's telling me to enter a password in Terminal but when I try to type it in, it doesn't type anything.
That is normal : type your admin password, nothing will be displayed, then hit the Enter key.
Tried the Terminal command, it went through, I restarted my computer, and nothing.
Is it safe to say my audio has malfunctioned at this point? I've tried resetting SMC, PRAM, and used Terminal.
Does "Sound" in System Preferences still reads "Digital Out --- Optical digital-out port" ?
Can you select "Soundflower" there ?
Couldn't Soundflower be the problem ?
Also try using AudioMidi Setup... (Applications / Utilities).
I doubt Soundflower could be the problem, because I've have that there forever and it never did anything.
Edit: Red light went on for a few seconds again. Decided to look in it and this is the best I could take a photo of whatever it is.
Is that white-ish grey thing in there a part of the Mac, or is that dust?
Gives me this.
There was dust inside, got it out, and now this.
I would say this points towards a mechanical problem in the audio port (?)
