ALC269 & VoodooHDA 0.2.2

[groppymac]

As sound is the only missing thing to get a fully working os x on my Notebook the only way to get some sound out of it is by installing voodoohda!

But the sound is totally distorted only if i move the mouse the sound gets clearer.

I searched a lot and found out that it could be somehow cpu related and added idlehalt=0 as Kernel Flags to my boot.plist.

This didnt work for me and so i wanted to ask if anyone had the same problem and found a solution?

Any help would be greatly apreciated!

What kernel and bootloader are you using?

 

Try installing Chameleon 2.0 RC2 (google).

[groppymac]

I'm already using chameleon 2.0 rc2 and also the vanilla kernel.

USB or PS2 mouse?

 

Do you have AppleHPET and AppleRTC loaded?

 

(Open System Profiler -> click Extensions)

[groppymac]

I'm using the built in trackpad for which i installed the ApplePS2 and AppleRTC is loaded, AppleHPET is not loaded.

[Beerkex'd]

Edit your Extra/com.apple.Boot.plist and add the string ForceHPET with the key y (see the Chameleon 2 docs)

 

And try using VoodooPS2Controller.kext instead of the one you are using now.

 

Are you using a disabler.kext? If yes, open it, look in the plist inside and tell me which extensions it is disabling.

Are you using a DSDT patch?

[groppymac]

Added now ForceHPET to boot.plist rebooted and it is finally loaded but no sound improvement.

 

I cant remember exactly but i choose something during installation that doesnt work with voodoops2 think it was acpi!

 

Im posting my disabler.kext because i dont really find the disabled kexts.

 

And yes i choose dsdt patch when installed os x because i had to use cpus=1.

 

In between thanks a lot for the help so far, i really hope i can get this working with your help.

 

Here is my disabler.kext plist.

The first one you don't need in the disabler unless your model identifier (System Profiler, Hardware) is MacPro3,1 or MacPro4,1.

Disabling the second one fixes mouse 'jumping' when iTunes or Quicktime is running. But many people don't have this problem, so you might not need it in the disabler.

Disabling the third one...is needed on many systems and is the reason why the disabler.kext was created in the first place. Some people can run it if the DSDT is properly patched and if they have an Intel Core 2 Duo CPU (don't know if it works with Core 2 Quad or Xeon CPUs). I can run it, but it is not doing any throttling or speed-stepping.

 

If you decide to take the plunge and try if your system will work with AppleIntelCPUPowerManagement.kext - by removing disabler.kext - you need to be ready to put back the disabler.kext somehow, in case it doesn't.

Remember you can always boot from your install DVD and use Terminal to restore a backed-up kernel extension. Put it in an easy to reach place like the desktop and make sure to set the correct permissions on it, otherwise it won't load.

Of course you will have to learn some terminal commands, but that's the fun part.

I don't know if it will fix your audio problems but it's worth a try.

 

Are you using an SMBIOS injector, or /Extra/smbios.plist?

Preferably you should be running a vanilla AppleSMBIOS.kext with no modifications, no SMBIOS injector (there are many different ones out there) and just use the smbios.plist in /Extra. Like this:

http://www.insanelymac.com/forum/index.php...t&p=1156867

Don't change your model identifier, changing it on a running installation can cause problems. If some information is missing when comparing to my smbios.plist in the link, try to find the right information that matches with the model identifier you use - don't use my iMac9,1 data if your model identifier is not iMac9,1.

And above all make sure the frequencies are right - this could fix your problem.

[groppymac]

Tried editing the disabler like you told with the only result that i couldnt boot osx.

I decided to make a fresh installation this time without smbios injector without acpi and with voodoops2 controller!

But sound problem is still the same!

What was interesting is that when i tried voodoo controller with trackpad the sound during the welcome video was good but when the mouse showed up i couldnt move it and the sound got bad.
