HELP! Cant change the volume on my macbook (Screenshot)
Happens both when i have something plugged into the headphone jack, and when i don't. Restarting did not seem to help.

1) Look in your headphone jack and check to see if there is a red light.
2) Check the sound system preference panel and see if sound is being output to "digital out" instead of "internal speakers."
If the answer to both is yes, then the computer is trying to output to the jack because it thinks there is something there (hence the red light). This is a decently documented problem (both here and on google). The problem tends to recur when you put something in the jack and take it out, but the computer doesn't realize that you've removed the peripheral. The solution either involves sending the thing back to Apple or poking around the headphone jack until you flip the detector and turn the red light off.

Lol I was having this problem today for about half an hour I was troubleshooting it and trying to solve the problem. I saw this thread and it said check for a red light near the headphone place and then guess what...?
My headphones weren't plugged in properly lolz.
Also I realize I bumped up an old topic lol.

hi i have the same problem with my macbook air, except I don't have any red light, the headphone thing didn't work and resetting the PRAM didn't work either. Happened about 2 weeks ago but then it was fine after a week and now once again after about a week it has started doing the exact same thing. I looked at the system preferences and checked my output device but none are showing. There are no output devices available and I cannot seem to install one.
Can anyone help?
