Launch the application 'Audio MIDI Setup' by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as 'Airfoil'), deselect it.Ħ.

If applicable, uninstall according to the developer's instructions ( not by dragging something to the Trash.)ĥ.

Built-in speakers or with headphones, it doesn't make a difference. The MacBook seemingly forgets that it has audio hardware, and behaves as if there is no sound hardware installed there is no volume control, and items are missing from the Audio section of System Report. With 10.10.4 audio was working as expected, however after upgrading to 10.10.5 audio ceases to work. Much to my surprise, I have found that installing the 10.10.5 update is breaking audio support on my Retina MacBook (2015).
