I had that problem after a forced shutdown while the system was delaying to boot in restore mode  (Command +R). After that, I had no internal speakers, built-in nor startup chime.

After some days trying every step I found in the Internet I was decided to change the sound board.

The computer was left all the night doing backup and in the morning without realizing it was sleeping I forced shutdown accidentally by pressing the on button too long. Surprisingly after reboot the chime came up again.

So there is my doubt. A forced shutdown may cause a system fail to no recognize the internal audio board?
