I've created a dsdt for my board Gigabyte EP35-DS3P using GA EP35-DS3P.txt and ALC 889a.txt. With the compiled dsdt.aml I am successfully running Lion 10.7 Vanilla with FakeSMC and for the sound stuff I use ALC8xxHDA/AppleHDA Rollback. No other kexts was necessary.

I still have sleep issues tough:
1. My PC goes to sleep properly but after waking up I get kernel panic.
2. I've tried using NullCPUPowermanagement - the PC goes to sleep and never wakes up again...
3. I tried to add patches LPC ICH9.txt + New HPET.txt and I still get kernel panic.
Would you please help me with further patching?

I don't think it's DSDT related, there are reports about it even on real Macs

Have you tried without the rollback audio kexts?

Good job Cassio! Thank you very much.

1.
I don't know how to revert from AppleHDA rollback (maybe I should have backed up the original first me noob or how?)...

2.
Combo Update 10.7 -> 10.7.3
This replaced the AppleHDA rollback to original I suppose.
Reboot.
Sleep and wake up works :)))))
No sound. :(

3.
Reapplied Realtek ALC8xx.
Reboot.
No sound.
(sleep+wake still works)

4.
Build new dsdt.aml
I applied
GA EP35-DS3P.txt
ALC889A.txt
ALC 889a.txt

5.
Reboot with new dsdt.aml
Still no sound
Applying AppleHDA Rollback (MultiBeast)
(still forget to back the original up - hmm)

6.
Reboot.
Sound is up :)))))
Sleep.
(crossing fingers)
(waking...)
Wake.
no kernel panic :))))))))) It works !

I'd like to ask which patch should I add for my Gigabyte EP35-DS3P rev 2.1 F6 and HDEF ALC889a onboard audio for audio?
- ALC 889a.txt (under HDEF Gigabyte)
- ALC889A.txt (under Misc)

I tried if I add either of them or both of them - so in all cases - the onboard soundcard works under Lion 10.7-10.7.3 but I still have to add ALC8xxHDA and AppleHDA Rollback with MultiBeast.

Is ALC 889a.txt (HDEF Gigabyte section) is enough for my dsdt.aml?
(original DSDT is 2-3 posts up attached as send.zip to my post)

You will always need ALC8xxHDA+AppleHDA rollback, or a patched Lion AppleHDA.

In DSDT part, the important is that layout-id coincides with LayoutID in AppleHDA, see here viewtopic.php?f=19&t=634

The layout ID is "0x75, 0x03, 0x00, 0x00" for my soundcard.

I'm already using a modified GA EP35-DS3P.txt by modifing the layout ID part of that patch (I've read about this somewhere).
Code:
into device label HDEF insert
begin
Method (_DSM, 4, NotSerialized)\n
    {\n
        Store (Package (0x04)\n
            {\n
                "layout-id", \n
                Buffer (0x04)\n
                {\n
                    0x75, 0x03, 0x00, 0x00\n
                }, \n
                "PinConfigurations", \n
                Buffer (Zero) {}\n
            }, Local0)\n
        DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))\n
        Return (Local0)\n
    }
end;


However both the "Gigabyte HDEF" and the "Misc" alc 889a patch already contains this layout id.
Does it matter which one I use in my DSDT?

If you edited GA EP35-DS3P.txt to fit your needs, you don't need another HDEF patch. I would use the one from "Gigabyte HDEF" since the mobo is Gigabyte.
