Macbook sound muted and no output devices shown when going into system preferences in sound.
My Macbook's sound is not working, the sound is muted and I am unable to uncheck the mute in system preferences and there are no output devices shown when going into sound of the system preferences.
Tried SMC, NVRAM reset, reboot and nothing is working.
Please Help, Thanks.
MacBook Air 13", macOS 10.14
