Thank you, this works with my 3-yr old rig.

 

Kalyway 10.5.1 updated with Kalyway 10.5.2 (no vanilla) - the kext that came with the distro doesnt work, left channel only.

 

P4 2.8GHZ

MSI P4MAM-V mobo

Nvidia GeForce FX5500

VIA AC97 VT8235

2GB RAM

 

For those of you who would like to skip the commands in terminal, you can do it the super easy way:

 

1. Download : AppleAC97Audio.zip from the first page of this topic and extract the .kext

2. Google search: "OSX86tools" and download - this is a great tool created by PCWiz

3. Install : OSX86tools to your applications folder. Run and choose install kext.

4. Change : Utilities> Audio MIDI Setup> Audio Output from: 41000hz to 48000hz

5. Enjoy : listening to stereo!

 

Of course dont forget to backup the original .kext before replacing.

My Os: Apple Leopard, from leo4all installer

my soundcard if detected using OSx86 utility:

 

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

 

80:01.0 Audio device [0403]: VIA Technologies, Inc. VIA High Definition Audio Controller [1106:3288] (rev 10)

 

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

I f I use installer AppleAC97Audio.zip, my  souncard not detected although I do the procedure in this forum using driver AppleAC97AudioVIA.kext . Then I try to install AppleAzaliaAudio.kext [.::installer can download in this forum AppleAzaliaAudio.zip::.], before install this .zip, I delete AppleAC97Audio.kext folder. I also backup(move) ApppleHDA.kext folder from directory /System/Library/Extension

After install AppleAzaliaAudio.pkg, I can hear sound from output my sound card, but output sound not correct. I only hear hiss or "hhhssszzzz".

 

 

 

I'm try change configuration according to http://forum.insanelymac.com/index.php?showtopic=18642

 

in AppleAzaliaAudio.kext/Contents/Info.plist

 

<key>IOHDAudioCodecVendorID</key>

<string>0x32881106</string>

 

then in ppleAzaliaAudio.kext/Contents/PlugIns/AppleAzaliaController.kext/Contents/Info.plist:

 

<key>IOPCIPrimaryMatch</key>

<string>0x32881106</string>

 

Then restart

 

After restart, the result from output sound not change, only hiss. Then I change format audio in "Audio midi setup" ('Applications' --> 'Utilities') from 2ch-24bit to 2ch-16bit. 

 

After change audio midi, my sound card working properly

Here's a new AppleAC97AudioVIA.kext so you can get stereo out of a VIA 8237R + ALC655 (I don't think the codec part matters as much as the controller)

 

Should work with any VIA 82xx chipset.

 

Hooray!

 

And this actually works. (10.5.2 on AMD 4200+, realtek AC97) Finally Stereo! my setup nears completion now. thanx

Many thanks to pattjin for posting the file.

Thanks to Proteo for the detailed step by step installation instructions.

 

It worked without any problems on my old computer assembled in 2007.

iDeneb v.1.5.1 OSx86 v.10.5.7, Darwin 9.5.0

MSI K9MM-V (MSI 7312) Motherboard with Realtek ALC655 Audio Chipset,

Northbridge: VIA K8M800 and Southbridge: VIA VT8 237R Plus

VIA AC97 Enhanced Audio Controller

 

I have a ATI Radeon 9200 SE AGP Graphics Card which is proving to be a

challenge to setup. Any help is much appreciated.

:(
