Tanks!!

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've attached some info on the panic.

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).


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.
