I want to say sorry already because I'm sure theres an answer posted, but I've been trying for awhile now to figure this out and finally resorted to posting a topic.

I have a GX520 that I've installed iDeneb 10.5.6 on, and everything is working great, except the sound. I'm trying to figure out what guide to use, AC97/ADI/etc and I don't know which one to choose.

The hardware is a SoundMax Integrated Digital Audio (ADI 198x ?? I think) by Analog devices, VENDOR = 8086, DEVICE = 27DE, the southboard chipset is an intel ICH7. Could someone please point me in the right direction??

Thanks everyone!

Hi! Have figured out your audio card exact model? install OSx86 tools, this tool have machine info tool, that gives you exact information. I have ALC883 on ICH7, but haent got it to work correctly. AzaliaAudio seems to work but only on 2ch. But i have 5.1 card.. Havent got time to develop byself aduio driver.

I have a Dell GX620 with the same audio chip. Here is what I did to enable the sound in my computer with iPC 10.5.6 installation.


1 .Make sure you have AppleAC97Audio.kext installed
2. Edit the file /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97AudioIntelICH.kext/Contents/Info.plist and add or modify the file with a section as follows


<key>ICH7 AC97 Audio</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.apple.driver.AppleAC97AudioIntelICH</string>
<key>ICH Type</key>
<integer>7</integer>
<key>IOClass</key>
<string>AppleAC97AudioIntelICH</string>
<key>IOPCIPrimaryMatch</key>
<string>0x27DE8086</string>
<key>IOProbeScore</key>
<integer>10000</integer>
<key>IOProviderClass</key>
<string>IOPCIDevice</string>
</dict>

3. Save the file and reboot the computer to see how it goes.



Good Luck!

Awesome, I'll give it a try and report back with how I made out
Thanks for the quick replies guys, this is a great community to be a part of.

hey angelohuang, I edited the info.plist file and sound come up on reboot
I might be doing something wrong, maybe its not loading the kext correctly. Where there any other steps you had to do to tell which kexts to load?
I wonder if there's a difference between the iPC and iDeneb release. I hope not.
Thanks.

These are a few things you can check
1. Do you have /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97CodecAD198x.kext installed? When I type "sudo dmesg" in terminal, there is a line says

AppleAC97CodecAD198x: 2-to-4 channel spreading enabled

Apparent, it is using that kext.

2. You may try to clear the extension cache using OSX86 Tools and and then boot with "-f" flag to see anything changes.

Hey guys. I have the gx620 and modified the plist but still am not able to get sound.

Any other adivce you might have?
