1. Tweak AppleHDA.kext to detect 3 Line Outputs: Green, Black, Orange.

3. Add new Aggregate Device
4. Click on the 3 check boxes corresponding to the 3 Line outs
5. Click on Configure Speakers
6. Select all 3 streams
7. Select Multichannel 5.1
8. Make sure all channels are properly mapped
9. Select Aggregate Device as output under System Preferences>Sound
10. Done
Here's my modified AppleHDA.kext as reference

Thank you so much for posting this! I had not been able to get the ALC888 chipset on my Gigabyte GA-965P-DS3 to work under 10.5. All I had to do was drop your kext onto the Kext Utility, reboot, and now I have sound under 64-bit 10.6. Your work is appreciated! |
