Here is my own compiled tutorial of the Apple Azalia 2 channel audio out only fix.

 

I take no credit, I just compiled this from multiple sources. Good luck!

 

----------

 

T60p and X60 Audio Fix:

Searched Google for: AppleAzaliaAudio.kext AD198

 

Got: http://forum.osx86project.org/lofiversion/....php/t2001.html

and http://forum.osx86project.org/lofiversion/...php/t18642.html

 

(BACKUP 1st anything you delete!)

 

1. Delete AppleHDA.kext & Cleanup a bit:

In Terminal, type:

sudo rm -rf /System/Library/Extensions/AppleHDA.kext

sudo rm -rf /System/Library/Extensions/AppleAC97Audio.kext

sudo rm -rf /System/Library/Extensions.mkext

sudo rm -rf /System/Library/Extensions.kext

 

2) Edit AppleAzaliaAudio.kext:

In Terminal, type: sudo pico /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/Info.plist

Search for (use hotkey= ctrl + w): <key>IOHDAudioCodecVendorID</key>

change the string to: <string>0x10ec0882</string>

Exit pico

sudo pico /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/PlugIns/AppleAzaliaController.kext/Contents/Info.plist

Search for (use hotkey= ctrl + w):
<key>IOPCIPrimaryMatch</key>

change the string to:
<string>0x27d88086</string>

Exit pico

 

3) Clean up the system:

In Terminal, type:

 

sudo diskutil repairpermissions /

sudo chown -R root:wheel /System/Library/Extensions/AppleAzaliaAudio.kext

sudo chmod -R 755 /System/Library/Extensions/AppleAzaliaAudio.kext

cd /System/Library

sudo rm -rf Extensions.mkext

sudo rm -rf Extensions.kextcache

 

chown -R root:wheel /System/Library/Extensions

rm /System/Library/Extensions.kextcache

kextcache -k /System/Library/Extensions

sudo kextload /System/Library/Extensions/AppleAzaliaAudio.kext

 

4) Then, reboot and enjoy sound out of two channels.

some thoughts about mute led on HP...

in windows, there is a HPQ buttons device (smth like this), and this device needs a driver! maybe it manages with volume control? maybe we need this driver in macos?

ive got HP nx7300

 

 

in device manager, does the HPQ buttons device have a vendor/device ID?

I have an HP nx7300 with the good old ad1981hd card.

 

I was searching on google out of despair and stumbled accross another project called ALSA (http://www.alsa-project.org/main/index.php/Main_Page), which is meant to get advanced audio functionality in linux. after having run out of codec dumps to use with taruga's AppleHDA patcher, it seems like a dump created on linux with this project might be helpful.

 

anyways, I don't have linux installed on my computer and the nx7300 can only run live CD's in safe mode for some reason  (which means I get less functionality) - so, what I'm trying to say is, can somebody pick up the gauntlet (and post a linux dump using this driver)?

 

worth a shot, don't you think?

 

also,

 

looking at the messages os x hands out while loading (-v, AKA verbous mode), I noticed it says something about AppleHDA failing to load because it can't find layout-ID something... is this a clue? I tried with my limited abilities to add layouts but to no avail.

 

am thinking of starting an HP notebook anonymous support group.

Hello, I think wee should add our dumps in post: AppleHDA Solution - Work in progress, LineOut,LineIn,HeadPhone,SPDIF,Mic working http://forum.insanelymac.com/index.php?sho...&start=2260 , Taruga is our last hope, only he can help us with it, but he needs dumps to do something.

maybe the sound drivers are ok already (including Port Configurations) as it works for IBM's. Maybe its all about the mute button and Sound will be available when the mute button gets turned off somehow. Seems this is a HP related problem only. So we just have to get that mute button deactivated.

Just my 2 cents..

Hi all,

I have a hp nc6400, and in some cases, 90% of time, the auto mute is gone.

It happened after installing 10.4.11 and 10.5.1.

I am using Azalia kext.

I think the reason is that I removed the AppleHWSensor.kext wich I didn't done before.
