Whoa- nice- haven't seen a LegacyHDA edit yet for this chipset- testing now

Awesome, thank you. I've confirmed this works on a ga-p55a-ud3 rev 2.

Yeah, it works, but only 2.1 speakers, with VoodooHDA 0.2.1 I can get 5.1 sound speaker. If anyone can get 5.1 sound please advise. Thanks

Thanks for useful and detail instruction.
All works excellent on GA P55-US3L rev2.3

Update 10.6.5 work without problem, after AppleHDA 10.6.2 rollback from Multibeast

 

[laguna1212]

DSDT was already up and running.
I installed the Legacy HDA extra/extensions download.
I installed the AppleHDA 10.6.2 from the rollback in Multibeast.
Running Mac Pro 3,1 (and tried 4,1)
Ran system utilities

Nothing

I don't have to edit the DSDT do I?

Yes you need to modify that DSDT file

 

[laguna1212]

I am using DSDTSE to edit the DSDT. Is there a good thread or guide that you know of I can look at. Haven't edited DSDT's before.

Hi guys! Can you help me with one thing: I don't know for sure - where I should write a section, that you write in this topic, in my dsdt.aml. I will wait for your answer. Thank you!
