Solved MacBook (Pro) 5,1 + Realtek ALC889A sound setup

Dear FreeBSD users,

I recently decided to revisit my attempts to install FreeBSD 10.x on an older MacBook 5,1 (2008-2009 series) device. It has nice, integrated nVidia graphics (GeForce 9400M), well supported by the binary blob and a Broadcom bcm4322 wireless adapter that is supposedly being worked on.
In essence, almost everything works as advertised...except sound.

The sound card in question is Realtek ALC889A that was put into MacBook and MacBook Pro 5,1 laptops. I did some basic troubleshooting, though with hardly any progress. I also read forum posts on our FreeBSD forums here, alas it did not seem like anyone achieved much success. Therefore, before we go into any technicalities, I would like to know whether anyone has actually made the Realtek ALC889A chip cooperate.

The primary goal is to get the integrated speakers to work, with a secondary goal of enabling hot-plugging of headphones to the jack port.

Is the card detected at all? If so, can you post the output of cat /dev/sndstat?

Click to expand...
That's the thing. The card is detected perfectly fine. alsamixer reports several channels and cat dev/sndstat shows that the speakers are selected as the default sound output.

EDIT - Relevant output below:

Any chance the device can be configured properly? :)

I am double-posting as I accidentally found the solution through trial-and-error based on gpio trickery some other people did. The below code in /boot/device.hints solved the problem:
Code: 
hint.hdaa.0.config="ovref"
hint.hdaa.0.gpio_config="0=set"
Apparently, sound was configured properly, but the speakers were set to 'off' as I read under device.hints() :).

Hi, I'm trying to replicate these comands but got the following:

fish: Unsupported use of '='. In fish, please use 'set hint.hdaa.0.config ovref'.
amgpuma@amgpuma-freebsd ~> set hint.hdaa.0.config ovref
set: Variable name 'hint.hdaa.0.config' is not valid. See `help identifiers`.

any clue how can I sort this out?
Many thanks

This is what I put in /etc/sysctl.conf for a 2009 Mac Mini:

Code: 
# 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
