@ Gatsby -- It may be an issue with "pin configurations" -- here's what I have in my DSDT for that section of the Device (HDEF); try this out and see if it compiles:

"PinConfigurations",
Buffer (0x18)
{
/* 0000 */ 0x10, 0x44, 0x11, 0x01, 0x20, 0x14, 0x01, 0x01,
/* 0008 */ 0x40, 0x4C, 0x21, 0x02, 0x50, 0x34, 0x81, 0x01,
/* 0010 */ 0x60, 0x9C, 0xA1, 0x02, 0xF0, 0x61, 0x4B, 0x01
}
}, Local0)

@ richiem: Thank you very much, I'll try these values on the weekend! By the way, did you achieve line-in/mic jacket activation on your machine with these values?

[richiem]

Sorry, can't speak to that -- I only use the green rear-panel output jack -- don't even have the front jacks hooked up and haven't tried the rear panel inputs yet. The few times I've needed analog inputs I've used a USB iMic. I never use headphones so don't know about that either... Funny that a retired audio engineer and loudspeaker designer should be so ignorant about his computer's audio functions...

just a small tip:
PinConfiguration has no meaning in DSDT
the config in the DUMMY KEXT (Legacy) override this
you can as well use

"PinConfigurations",
Buffer (0x0)
{}

and the result will be the same

[richiem]

@winstonace -- thanx for the tip; however that wasn't my experience -- I had a different set of codes in the pin config originally (from another DSDT), and sound didn't work until I put this set in, and I didn't change anything else that I can remember. I hope we hear from gatsby, it will be good to know one way or the other....

Thanks you post for ALC889A

Hi, I have a Gigabyte GA-EP45-UD3P (rev. 1.1) as well. I'm still trying to get my sound to work with 5.1, without the popping noise. right now, i'm on a fresh install with no sound. Can someone send me what you have, and tell me what to do with it?

this is what was happening to me before this fresh install

It's the weirdest thing in skype...
I'm running a 'gigabyte ga-ep45-ud3p' on snow leopard, installed from a retail dvd, using these sound drivers.
I can hear someone, and they can hear me, if they call me.
But if I call them, I can't hear them, but they can hear me.
Also, if I type in the chat area with anyone during a call, whether they've called me, or i called them, I can't hear them, but they can hear me. My sound gets muted if any sound comes from skype other than the voice conversation.

i have to disable all skype sounds for a call's audio not to be interupted.

i downloaded the zip below where it says
'Fixing for 10.6.2 by removing BuiltInHDA and including HDAEnabler.kext' in this thread
and installed the LegacyHDA and HDAEnabler kexts, and that's it. no dsdtl (or whatever you call them) files or anything.
then i used aggregate device to create 5.1.
the sound is a bit buggy.

is there a newer, better way to get 5.1 on my ga-ep45-ud3p?

i'm a noob. i have been on os x for maybe 4 days, for about 30 minutes a day

[edit] a kind member in the #snowleopard irc channel was nice enough to create most of the files in this 'Extra' zip file for me, but after i applied them all, and ran pfix and repaired disk permissions, i ended up having a blank blue screen, and wasn't able to boot without -x

[dannymichel]

has anyone gotten the front and back mic and headphones working yet?

[holyfield]

I should thank everybody for hard work!

Mobo: GA-X48T-DQ6 (with ALC889A audio)
Installed OS: Mac OS X, Snow Leopard, 10.6.4

I downloaded kext and updated my dsdd.aml and audio is working like a charm. Haven't tested yet the 5.1 audio, but I to it, but it should be easily available, as all outputs are mapping correctly into my 5.1 speaker, just some aggregate device is needed to create.

But I'm curious, does ACL889A device can work without kext, because if I used this dsdt fix below, I had sound trough green output without additional kext.

So, I believe there should be some solution to use only dsdt fix. Any suggestions? If we get correct replacement for rows marked with pink below, we should be capable to get ALC889A to work without additional kext.

                }

            }

By the way, the most important part is only the Method (_DSM, 4, NotSerialized) {...} part, which defines how Mac OS X can communicate with audio device.

Some notes for others, who are about seeking for working audio!

Please remember, You NEED one of solutions models below:

A
1. Fixed dsdt.aml file (your mobo & bios version specific) under /E/E

B
1. Fixed dsdt.aml file (your mobo & bios version specific) under /E/E
2. Some additional kext under /E/E or /S/L/E (Reccomended is /S/L/E)

The best option is of course solution A, which is bulletproof against OS update. Anyway, if your audio does not work right out of box, then you need to do some hard work to get it work (hard means - you should educate yourself a bit about DSDT etc.

Surprising !
I inserted this modification inside my dsdt and bingo ! Sound is now working with AppleHDA.kext without any other addition like LegacyHDA etc....
