My audio settings were normal, and when I was having other problems with my computer I restarted it. However, when I booted it up again (on safe boot), the audio is on mute. There's no sound symbol on the top Finder toolbar, and when I go in Sound Settings under System Preferences, everything is check "Mute." However, everything is greyed out and I can't uncheck it. There's no red light from my headphone jack or anything, so I have no idea how to get my sound back....
The other problems I'm having that may contribute to this: I had a regular software update yesterday that I installed, and when I had to restart my computer, the apple logo on startup with the wheel wouldn't go away, so I had to boot up with safe boot. Since then, most of my iTunes library has been erased, and Firefox hasn't been working properly, and, of course, I have no audio. Help? 🙂
