Some people said it worked for them.
I tried, but nothing, I've actually loaded and unloaded the extensions from the folder that they are not and the folder that they are in.
It did not work.
I do have to say that before it sleeps, the sound is fantastic, both in and out.
After the computer comes back from sleep, the mic is apparently OK, the sound out is non existent.

Depending on where you have installed AppleHDA.kext your rc.sleep would read either

#!/bin/sh
/sbin/kextunload /System/Library/Extensions/AppleHDA.kext/

or

#!/bin/sh
/sbin/kextunload /Extra/Mini9Ext/AppleHDA.kext/

Apply the same path for rc.wakeup

I noticed that adding a 3 second pause in rc.sleep script helps a bit on restoring the sound on wake (sometimes it doesn't unload the kext properly before going to sleep?)

#!/bin/sh
kextunload /Extra/Mini9Ext/AppleHDA.kext/
sleep 3

The Mic finally works using this method. Much thanks! I have not tried the sleep test yet using SleepWatcher.

Question, when and if I run the NBI-.8.4RC4 again, will the AppleAzalia.kext adn PatchedAppleAzalia.kext files load in again? Which will need to be removed, correct?

Yes, unless you remove them yourself from the installer.

make sure you get ALC268_3.kext.zip (I attached it here if you don't want to register)

To get the sound working after wake from sleep I used SleepWatcher configured as described in this thread (Method 1)

Two methods to get sound after sleep on a 10v

Make sure you remove AppleAzalia.kext and PatchedAppleAzalia.kext or VoodooHDA if present.

Works like a charm on my Mini 9, no choppy audio after sleep

I did the procedure described above and the mic works for the first time every on my Dell Mini 9! Thanks!

But now I have lost the sleep wake up. I have to hard restart to wake up each time. I have installed the SleepWatcher but don't know enough to be able to modify?

Any suggestions on how to get the sleep wake back?

My configuration is: Mini 9, NBI 0.8.3RC4, Snow Leopard 10.6.2, 32gb RunCore SSD.

Thanks, Chuck

tommyv,

Sorry, but it does not work.
Apparently once unloaded, the extension does not get loaded.
I tried kextutil and it showed some problems.

Warnings:
The booter does not recognize symbolic links; confirm these files/directories aren't needed for startup:
/Extra/A90Ext/AppleHDA.kext/Contents/CodeDirectory
/Extra/A90Ext/AppleHDA.kext/Contents/CodeRequirements
/Extra/A90Ext/AppleHDA.kext/Contents/CodeResources
/Extra/A90Ext/AppleHDA.kext/Contents/CodeSignature

I am not clear.... are you referring to SleepWatcher or are you referring to the AppleHDA.kext?

Which are you suggesting I try to remove?

I upgraded to 10.6.2 tonight, this kext got sound and headphones working for me. I'll try it out with sleep tomorrow. There is a very low buzz coming from the speakers when I'm in headphone mode though...nothing major but its not silent.

@meklort: hows your patching going?

[maddog]

SleepWatcher does not work for me.
When I unload the extension it does not come back to life anymore.
However, before you sleep, the sound works great.
I have3 no buzz or anything. Perfect sound both in and out.

The error message3s that are quote3d in my previous message is the error I get using kextutil to load the extension.
I might move the Apple extension to its appropriate place and see what happens.

Alright, I've got it.
At least in my Vostro it works fine if I do the following, put the AppleHDA.kext in the /System/Library/Extensions/
Now, whether or not we have SleepWatcher, the extension is unloaded when the computer goes to sleep.
When the computer wakes up, the rc.wakeup command makes it automatic to upload the extension, however, if one wants to forego of this command line, either via an AppleScript or via command line typing:
sudo kextload /System/Library/Extensions/AppleHDA.kext/
--> prompt for admin password

will upload the extension and sound is back on!

Thanks for the original post and the follow up.
Great forum this one...

So this kext goes in /Extra and the dsdt.aml replaces the one in /Extra as well? Any other steps after that?

[deadlyvirus]

I got SleepWatcher to work for me. It's dirty, but it works. Headphone on SL is what had me on Windows.

Does someone else encounter this bug ?
For information : appleHDA.kext is in S/E/E and I deleted original kext from S/L/E.

Thanks for any feedback.

You mean like a little click? I get that every few seconds when nothing is playing. I don't know if there is a fix.
