Volume locked in MacBook Air

I have a MacBook Air 4GB. OS X Yosemite is installed.

The volume appears to be locked. When I press the volume keys, all i see is the speaker icon with a cross underneath. It won't let me adjust it in the toolbar. In settings > sound, there is no input or output devices found, nor will it let me adjust the output volume from there.

I tried restarting the computer in safe mode, resetting the SMC, force quitting the coreaudiod, plugging in headphone/usb speakers, and nothing has worked.

Please help. This is really annoying.

I had the same problem. I resolved it as following:

Go to System Preferences -> Sound -> Output. There should be item 'Internal Speakers (type: Built-in)' selected. In my case, 'Internal Speakers' were not present, rather there was 'Digital Out' selected and below message 'Volume cannot be controlled'.
I plugged in headphones. The selected device changed to 'Headphones'.
Unplugged the headphones. 'Internal Speakers' now appeared and were automatically selected. The volume control started to work.
