Fixing sound (ALC882) on an Intel 945 chipset

[thrunner]

Try this...Everything else failed, but this worked like a charm...Using the 945G chipset..

http://forum.osx86project.org/index.php?showtopic=8864&st=0

Yes. Confirmed in 10.4.5 Asus P5LD2-VM (input and front audio not working though). It is not enough to edit plist vendor IDs for AppleAzalia. Also required disabling of AppleHDA.kext (moved to Extensions.disabled folder:

945G's Realtek ALC882 instructions for 10.4.3 (8f1111)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

To get 2- channel sound you have to move AppleHDA.kext out of the Extensions Folder and replace the AzaliaAudio with this one, repair permissions and enable sound in the bios.

Installation instructions

----------------------

 

Download the file

unzip the file to your desktop

open terminal

do the following:

 

sudo -s

enter your password

cp -r /system/library/extensions/AppleHDA.kext /system/library/extensions.disabled

cp -R /System/Library/Extensions/AppleAzaliaAudio.kext /System/Library/Extensions.disabled

cp -R /Users/YOUR USER NAME HERE/Desktop/AppleAzaliaAudio.kext /System/Library/Extensions/

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

kextcache -k /System/Library/Extensions/

 

then you're done!!!

reboot system

any new information regarding getting the inputs working?

[s.h.a.r.p.]

i found out i have conexant hda for my sound card. same id's for the audio hub, though. i have tried a couple programs and none of them seem to give me the id's of the vendor. any tips?

 

EDIT: i think i got it:

sound - vendor: 14f1, device: 5047

VaiOSX seems to be the resident expert on this:

 

run in terminal:

 

ioreg -l

 

The command line in the terminal for directing to text file is :

 

ioreg -l > /username-ioreg.txt

 

http://forum.osx86project.org/index.php?s=...indpost&p=71710

Also, IOAudioFamily does not show up in System Profiler. When I try and load it, it tells me it's already loaded, but it still doesn't show up.

 

 

The best way to really know if your kexts are loaded is to use kextstat in the terminal :

 

kextstat | grep IO

 

You can replace IO by any strings (e.g if you type ATI it will shows all the loaded kexts with the name starting with ATI)

 

Don't forget that it's case sensitive.

I find that booting with Ubuntu Linux LiveCD can be helpful for finding certain device and vendor Ids.

 

Does anyone know if there is a parallel for onboard sound which has a vendor ID of 8086, a device ID of 24c5, and for which I have tried almost everything I can find to get it to work? I have updated the AppleAC97AudioIntelICH.kext, and updating AppleAC97Codec, etc. If there is a Controller that I have to update, I will do it, if the darn thing will just work.

[Doosje]

Strange things.

I have an Asus w2jc laptop and the sound icon apears, but ...now sound.. :S

not on my laptop .. not on the 'jack'

i have 10.4.6 installed ..

my ALC882 is on Intel 82801GBM ICH7-M - High Definition Audio Controller

 

is there something i missed ?

[asstastic]

For those who are running windows and need device IDs go to the windows device manager for the audio chipset vendor and device info get the properties for your audio card under "Sound, video and game controllers", my ALC883 was listed as Realtek High Definition Audio

under the details tab you will first see a string like this:

HDAUDIO\FUNC_01&VEN_10EC&DEV_0883&SUBSYS_1025160D&REV_1000\4&AFF89C6&0&0001

VEN_xxxx is the vendor ID

DEV_xxxx is the device ID

 

BUS ID's can be found in the System Devices menu of the Device Manager under "Microsoft UAA Bus Driver for High Definition Audio

 

also, the audio on my Aspire 5672 is working sporadicaly, ie only after booting OSX from windows and sometimes while the OS is running, i assume this has something to do with the audio controller bus not always being initialized. the device always shows in the sound settings panel whether or not i actualy get sound. so the question is, is there some way to force the bus to initialize on boot and stay that way?

[MacMartin]

I tried all of the above, but stil I get this message:

kextload: extension /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/PlugIns/IOHDAudioFamily.kext is not authentic (check ownership and permissions)

kextload: extension /System/Library/Extensions/AppleAzaliaAudio.kext is not authentic (check ownership and permissions)

 

I repaired all permissions, but here's the result:

 

**********

Aug 15 22:36:00: Disk Utility started.

 

Repairing permissions for "OSX"

Determining correct file permissions.

 

Permissions repair complete

 

 

The privileges have been verified or repaired on the selected volume

I can't seem to find the solution

 

 

 

I installed Myzar 10.4.6 at a second hdd, copied the kext, edited it and now sound out is working. Hope to get SPDIF workin'

[lazyxor]

Did you have sound input, MIC, and multichannel support ?

 

After trying the solution on 10.4.5 output works, GREAT THANKS to author, but no input and multichannel. Can it be fixed?

[Taruga]

Can anyone use the attached .kext and tell me if the input works, I have it in my system and Input Device appears. But didn´t test it.

 

Thank you

 

ps - 2 downloads, no feedfack ?!

[MacSimizeDenver]

Sorry Taruga,

 

on a 945P chipset (P5LD2 deluxe) it doesn't work. I tested it with Snapz Pro X.

 

I puted the extension in the systems extension folder and rebooted - there was a message screened that the extension can't be loeaded because it isn't compatible to the OS bla bla.....

 

Line-In doesn't work for me.

[Taruga]

What OS X version are you using ? I´m using 10.4.7. And this .kext is for pelo who have already sound output. Because you also need the AppleAzzalia for output. I´m going to test it now at my other board, an Asus P5LD2-VM (my other one is P5LD2-VM DH) and a will edit my post later if it works at this one too. If it works, it should work on your P5LD2 Deluxe. I can see the device sound input, but I have nothing to test it if it really works.

 

Edited - Ok, I´ve tested on a P5LD2-VM and P5LD2-VM DH and it appears the Input Sound device.

 

I´m using the following .kexts and I send you screenshots of input and output devices. Sound output is works fine, input not tested yet.

 

I unziped the files to / and used

 

cp -rfv /AppleHDA.kext /System/Library/Extensions/

cp -rfv /AppleAzaliaAudio.kext /System/Library/Extensions/

rm -f /System/Library/Extensions.mkext

rm -f /System/Library/Extensions.kextcache

disktutil repairPermissions /

reboot

I put it in the extensions folder, repaired permissions and rebooted. After the reboot line-in showed up in the sound prefernces. Then I had to restart because of some XP-stuff, but when I booted back to OSX the line-in was gone.

 

When it showed up, I booted without anything connected to the line in. Th second boot into OSX was with a microphone connected.

 

EDIT: Tested with Myzar 10.4.6 updated to 10.4.7 @ Asus P5W DH Deluxe

[MacSimizeDenver]

well, I far away from knowing Terminal...

 

that's what i see if i enter your first line of code in Terminal:

 

Last login: Tue Aug 22 18:17:25 on console

Welcome to Darwin!

eye-tvs-computer:~ KayK$ cp -rfv /AppleHDA.kext /System/Library/Extensions/

cp: /AppleHDA.kext: No such file or directory

eye-tvs-computer:~ KayK$

 

 

Ah...what's to change?

[Taruga]

MacSimizeDenver, unzip the files , click on your hard disk and you will see folders like Applications, Library, System, etc and drag the unziped files there (That´s the / )

Then the cp command will find the files at /

[MacSimizeDenver]

Got it and done it. After reboot I also see the input active - but it doesn't work. I plugged in a mic, I connected it with a headset ... no active input recognized by the Mac.

[Taruga]

Ok, thank you guys for testing it. I will keep trying to get the damn input to work. You can delete AppleHDA.kext to get back to normal.

[MacMartin]

Taruga, THX and keep up the good work!

 

 

 

I hope, when you get it to work, SPDIF is the next thing. I'm thinking about buying an external sound card, but if you succeed, I don't need to buy.

[NRGZR]

Taruga, i can help u with testing.

I have same mobo (ASUS P5LD2-VM) and some sound devices for testing input. connect with me by icq - 165264 if u need my help.

[Rene204]

ok, i have test it too. but the same results, audio-midi-conf. show me two inputs, one digital and one line in, but still no one is working.

the volume slider is in mute, but still sound,equal, which setting is set up. sound like line out, every setting the same volume.

after connect or disconnect the jack, the slider goes down to mute.

 

we have to work again...

 

Thx a lot... Rene

 

ok, got an realtek ALC882, on AOpen MB i945GTm-VHL.

[MrBryan]

I have a P5LD2 and have been trying to find a solution to this forever also ( getting inputs to work)

 

 

I'd love to help testing, too, if I can be of any assistance.

 

Through searching, I have seen some claims that a appleHDA kext from 10.4.3 allows inputs to work -- i've never been able to test it as I only have 10.4.6

 

Thanks for working on this,

 

Bryan

[jtekky]

iv'e tried this and my sound still doesnt work.. i dont know what im doing wrong... when i check the 2 strings its the right vendor id and device but my sound doesnt work.. i have a intel d915gvwb mobo with the onboard soundcard

[Galen]

What mystifies me here is that the exact problem you describe happens with the 915 mobo and ALC 880 - you have to get the audio initialized with another means. Once going, OS X can run them. However, the 915 and ALC 880 should already be working and automatically initialized, based on what I'm reading.

 

The problem was, when I was last hacking at it, they were not working. The only means of initializing the audio was modifying one of the drivers in such a way that it would kernel panic the machine at startup or booting into an OS that properly supports the ALC 880.

 

Any comments on how to get the 915 / ICH6 / ALC 880 working? The problem seems to be the same, but the solution isn't quite the same...

[Galen]

A few people have asked about how to explore the device IDs, etc. present on your system. I give you the elegant, OS X solution: IORegistryExplorer.app

 

It's located at:

/Developer/Applications/Utilities/IORegistryExplorer.app

 

Don't see it? Install the Apple Developer Tools to get the /Developer directory on your drive. If you don't have the Apple developer tools, simply head over to http://developer.apple.com/ and sign up for a free account. From there, just download the latest "XCode Tools" - a fairly large .dmg file - and install it.

 

I had previously used this in exploring my hardware, particularly to get the IDs of sound devices. It's quite handy. You'll find the audio devices nested under the PCI bus. It provides a lot of data, not all of which I completely understand - such as how the driver status works - but it seems few people know about this tool.

[priyaradha]

I have 10.4.7 and i have a realtek A882 and the same chipset it wont work i have been trying, but i System Extension cannot be used error, even after using disk utitly, and when i use the chown cmd line i get opperation not permitted any ideas???
