Question: my MacBookAir has no sound
I have a MacBook Air (13-inch, Early 2015), OS X El Capitan, processor 1.6 GHz Intel Core i5, memory 4 GB 1600 MHz DDR3, graphics Intel HD Graphics 6000 1536 MB.
The sound is not working and I can not manipulate the volume (first file attached).
I have reinstalled the IOS with cmd+P+R. Nothing was improved.
The system shows that there is no input/output sound device.
Please help me!
MacBook Air, iOS 10.3.3, OS X El Capitan
