A successful audio installation is required for working OS X/AppleHDA.kext audio. Most 'No audio output (input) devices' errors are caused by an incorrect installation; usually, the wrong choice is selected. Of all the audio choices available, only one choice enables Realtek ALC audio for a specific system. The correct choice results in working audio devices.
If System Preferences/Sound/Output shows audio output devices, see No Sound - Realtek ALC AppleHDA
Note: OS X/AppleHDA.kext does not support specific hardware, see Unsupported/Non working Realtek ALC AppleHA, Post #1, Audio - Realtek ALC AppleHDA for workarounds.
