Solving the cracking problem on VoodooHDA

[lightxspeed]

The cracking problem of the new VoodooHDA can be solved, the way is to unload the VoodooHDA.kext before it go to sleep and reload it back when the computer wake up.

First of all download the attachment and install both sleepwatcher.pkg and SleepWatcher StartupItem.pkg, then edit '/etc/rc.sleep' and add at the front :

Code: Select all

kextunload /System/Library/Extensions/VoodooHDA.kext
sleep 1
kextunload /System/Library/Extensions/VoodooHDA.kext

edit '/etc/rc.wakeup' and add at the front :

Code: Select all

kextload /System/Library/Extensions/VoodooHDA.kext

that's all!!

you will find that the icon in the menu bar disappear after wake up, just go to system preferences -> sound and click 'show volume in menu bar' to make it back. In fact it can be finish automatically by applescript but it's not useful for us which we've got a 'Fn + left, right' keys to control the volume.

reference
I'm using ideneb v. 1.4 and updated to Mac OS X 10.5.7, everything work fine.

I can edit the rc.sleep and rc.wakeup now.

I can get the computer to uninstall the kext through rc.sleep

but I can't get it to reinstall the kext through rc.wakeup.

Can anyone help?

I am more curious to know if this sleepwatcher can be used to disable the internal Bluetooth upon sleep, and re-enable it upon wake. Anyone care to comment?

I have the same idea but I don't know which is the kext for the internal bluetooth.

sorry to help hi-jack this thread, but here is a post that put on a bluetooth thread, it seems to tell what at least one of the bluetooth kext used.

I am not sure if anyone else has seen this error before, it happened today when I was closing my lid. I knew it would not sleep, anyway this is the first time i have seen this:

System extension cannot be used

The system extension "/System/Library/Extensions/IOBluetoothFamily.kext/Content/Plugins/BroadcomUSBBluetoothHCIController.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.

i am not sure if this will help solve the issue, but maybe it can help.

in addition, there is someone who has reported success with unloading and reloading bluetooth to get sleep, it is from thread:
viewtopic.php?f=15&t=2066

in case anybody wants to research further, I can get both wireless & bluetooth to work with sleep.
However it means removing 'IOUSBFamily.kext' entirely from '/System/Library/Extensions/'
this means that USB devices are not recognised, but in this state both bluetooth & wireless will work together and the system will sleep.
When you need usb you can drag IOUSBFamily.kext backinto the folder, becasue even if errors are reported it will start to work with external devices. (use ktext helper to resolve errors)

not an elegant solution at all, but means someone who knows a bit more may be able to work out the issue in that file that stops bluetooth being on for sleeping

i hope that this can help!

I can confirm that this happens on another machine. The VoodooHDA driver uninstalls fine when going to sleep. But when I bring the computer out of sleep, the driver sound does not work.

I dropped to a command prompt and ran the commands as sudo to see what happens

Unloading the drivers works fine.
sudo kextunload /System/Library/Extensions/VoodooHDA.kext
sudo kextunload /System/Library/Extensions/VoodooHDA.kext
Running this command twice as above unloads the sound driver. Entering the command once just generates an error.

Running
sudo kextload /System/Library/Extensions/VoodooHDA.kext
Loads the driver just fine. But I have no sound unless I restart my computer.

I am using the 0.2.2 VoodooHDA kext.

EDIT: For clarification. The sound driver does load, and I can see the volume control appear when I adjust the volume with the keyboard. There is just no sound being output. A restart is required to get things working again.

As I've tested, making it sleep once again then wake it up and the sound may work. You may try.

any updates of whether this is possible for BT as well?

I've been meaning to try this, but can you tell me why there are two "kextunload" entries in the sleep.rc file, with "sleep 1" between? I just like to know why I'm running a certain command and what it does.
