That is only half the story.

Kamal, read this thread carefully and in detail. By the endc you will understand what is involved to get audio to be perfect.

I didnt manage to do it because at the time I didnt understand the difference between Leo and SL kext caching, so even if had done it right, it would never work.

Probably next holiday break I will attempt to patch dsdt again

If you get the your dsdt patch to work, does your patch work for me? Or must i patch it too?
Is it not the same computer?

Best regards

Kamal

dsdt works like this, more or less in simple terms,

Bios <-> DSDT <-> Operating System

It is a table of code, extracted from specific Bios information, not only generic (how much RAM) but specific to graphic memory, audio card special features, sleep mode and lot of extra.

OSx reads Bios made for Mac, so dsdt is a little different for PCs, but highly compatible.

You can open up the dsdt and fix all the issues, that part is a bit tricky, but not dangerous at all.

So, unfortunately, yes, you have to make your own dsdt.

But, since our systems are so very similar, most our issues will be the same, so we can share the code for you to fix it too. But you will have to manually insert it yourself.

Unfortunately I have no idea when I will the time and courage to start this task...

I will see if i can manage anything of it to day maybe i will succed.

But later to day. Hope it will work.

Best Regards

Mine was AZAL, had to change to HDEF. See, one of the reasons you have to make your own dsdt patch, decompile, fix, recompile.

Then, quick ApplHDA patching and it should work.

Kamal, I do warn you though, that I had SERIOUS issues that made me have to re-install SL all over again. So be sure to back-up all important info.

It is not an easy job, so unless you use Mic In all the time, it would be better just to go out and buy a compatible, cheap, USB headphone with microphone, or just microphone, or a simple USB soundcard.

Send me your file let me see it.

Maybe i looked at wrong place.

Hi Guys,
I have an Acer Aspire 6935, it runs perfect with Snow Leopard, but there is one problem.

First I didn't installed it with this tutorial. I installed it from a external Kalyway 10.5.2 Hard Drive.
(Format Hard Drive, Insert Retail DVD, open OSInstall.mpkg, install SL to my Hard Drive ...) and I installed Chameleon RC3 with Terminal to my EFI Partition. Snow Leopard starts, only sound didn't work (now it works with VoodooHDA), but my battery isn't reorganised correctly.

The battery doesn't load... , the system crashes when starting with battery or removing the cable. (Black Screen but Notebook is still running.)

Also Standby or Hibernation isn't working. The Screen goes black but the notebook is still on like the battery error.

That's why I think it's only one error.

Here is a list of my kexts, hope you could help me:

EFI:

voodoops2controller.kext
openhaltrestart.kext
voodoobattery.kext
attansicL1eEthernet.kext
LegacyAppleAirportBrcm4311.kext
fakesmc.kext
PlatformUUID.kext

SLE:

VoodooHDA.kext

Any idea which kext is missing?

Kamal - ok, here you go, let me know what you find out! Anyone finding this post, unless you have my exact and perfectly same model, do NOT use this for your installations!

Drakulix,

The sleep/hibernation problem is one of the most common problem for everyone. The only way to fix this properly is to manually patch the dsdt.aml file, just like Kamal is trying for audio. So please refer back a couple of posts back for some info.

This is one of my goals too, basically, sleep and mic in are the final thing I need to have to perfect clone of a macbook pro. But I dont have much time for this at the moment.

About the battery manager. I too have experienced KP when taking out the power plug and running the battery. But that happened like, once only! Since then, stable and good readings. I would suggest you run Kext Utility app and repair permissions.

KamalAhmad · #59 11-01-2009, 11:59 PM

I used your dsdt.aml file and it works.
Worked like my org. dsdt.aml file i used before..

Did you change anything in your dsdt.aml file?

This is my org. dsdt.aml file in the attatchment.. Im using yours dsdt.aml file know.
Does that mean that you have exact my model.

BEST regards

Kamal

Glad to hear it! But what do you mean, you have mic in now?

Yes, I changed the AZAL entry to HDEF, so that AppleHDA (patched) or Voodoo recognize it.

No, it doesn't mean we have the same model ( I dont have blue-ray, graphic specs are very different for instance 1GB gddr2 vs 512 gddr3)) but since it so close, it worked... For instance, your audio might have worked but could be left without graphics.

Imagine you used a dsdt from another brand or entirely different Acer line, you might not be able to even boot

great news!

EDIT: Oh, ok I understand now, you have audio just like with your own original dsdt. That is to be expected, as with Chameleon and special kexts, most of modern computers work 95%. It is the special features that fail, like wake/sleep/hiberbation, microfone/spif 5.1, external monitor or HDMI, ethernet for some people, etc... For that, you have to manually patch your dsdt
