Sound Device • [Solved] How to fix sound on macbook

added the following to /boot/device.hints for speaker audio with the help of the info from link:

hint.hdaa.0.config="ovref"
hint.hdaa.0.gpio_config="0=set"
hint.hdaa.0.nid20.config="as=4 seq=15"

Added the following to the /etc/sysctl.conf

# cat /dev/sndstat
# -> pcm0: <Realtek ALC889A (Analog)> (play/rec)
# -> pcm1: <Realtek ALC889A (Rear Digital)> (play/rec)
# -> pcm2: <Realtek ALC889A (Rear Analog Headphones)> (play) default
# Below to set sound to pcm2 (rear analog headphones) on Mac Mini
dev.hdaa.0.gpio_config="0=set 1=set"
hw.snd.default_unit=2

Not sure I needed these few options in sysctl.conf but there there.

rebooted with sound through speakers & headphone jack, also microphone works. Oh and i did use a usb sound card while i had no sound and that worked too.

Thanks!
