Pergunta: Macbook Sound Greyed Out
Hi! Thank you in advance for trying to help. You're amazing.
My Macbook Air (13-inch, Mid 2011) running High Sierra suddenly has no sound anymore. I really didn't notice what might have triggered it.
The volume icon on the task bar is greyed out.
Preferences > Sound > Output only display my Apple TV as an option
Pluging an earphone doesn't change anything
Tried reseting the NVRAM (screen blinked a lot, but nothing changed - How to reset NVRAM on your Mac - Apple Support)
Tried some terminal commands (https://discussions.apple.com/thread/4202694). Nothing happened.
There is no red light in my phone whole
Tried manually deleting Library->Preferences: Audio
