Mini 9/A90 Sound Fix #279

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I posted this as a comment in issue 18, but I figured I'd make my own issue so 
I can track this. I 
found a solution that works flawlessly under 10.6.3 for audio in and out on the 
mini 9. Tested 
speakers, headphones, built in mic, and an external mic.. for the first time 
everything works!

I suggest adding this as a replacement for Azalia audio currently in use in 
0.8.4 RC1. These steps 
were performed on a fresh 10.6 install done with NBI 0.8.4 RC1. Upgraded to 
10.6.3, let NBI do 
its thing at boot and did this:

1) Remove the AppleHDA.kext from /Extra/Mini9Ext/
2) Add ALC268.kext to /Extra/Mini9Ext/
3) Add HDAEnabler.kext to /Extra/Mini9Ext/
4) Run UpdateExtra
5) Reboot

Everything works now. The two necessary kexts are attached. Kext written by

BTW, I realize there are better ways to do this, but the bottom line remains 
that this *works* and doesn't have any 
adverse effects on the system/sleep/anything else.

I can confirm this works. Two caveats: 
   1) I had to also put a copy of AppleHDA.kext from 10.6.2 in the folder with these kexts
   2) I get a slight burst of static on boot.   Its low volume and last less than a second, more than worth it to have functioning sound/Mic.
