Ok I have a Fix for Most AD198x sound cards in OSx86 10.5.1 and 10.5.2.

 

Load Applications/Utilities/Terminal

 

sudo -s
Enter Password:
cd /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97CodecAD198x.kext
chmod 644 Info.plist
nano Info.plist

 

Scroll Down Until you see:

<key>PNPVendorID</key>
<string>ADS75 ADS74 ADS73 ADS72</string>

 

Change it to:

<key>PNPVendorID</key>
<string>ADS78 ADS74 ADS73 ADS72</string>

 

Hit (APPLE)+(0) then (APPLE)+(X)

or on PC

(CTRL)+(O) the (CTRL)+(X)

to Save the Changes

 

Now Close Terminal

 

Load Applications/Utilities/ Disk Utility

and Click Repair Permissions

 

Wait for this to Complete

 

Once it is complete Load Terminal Again

sudo -s
Enter Password:
cd /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/
kextload -t AppleAC97CodecAD198x.kext.

 

Close Teminal

 

Open Terminal Once More to make it Load this kext every time you boot up.

sudo -s
Enter Password:
rm /System/Library/Extensions.kextcache
kextcach -k /System/Library/Extensions

 

Close Terminal and Repair Disk Permission to be Safe

reboot

 

Once Rebooted

Load Applications/Utilities/ Audio MIDI Setup

 

Click the Properties For Drop Down and Choose the bottom AC97 Audio (PCM)

Change Format on the Right Pane to (6ch-16bit) or (6ch-32bit)

Varies per your motherboard.

 

Click Configure Speakers

Click Multichannel, Change Drop Down Menu to Stereo

Change "left front" value to 3

Change "right front" value to 6

 

Enjoy audio on all AD1986a ,b, or c card from HP, DELL, and Compaq

I have tested this on a Dell Laptop and Desktop and had friend use it on HP and Compaqs

 

If you have any issue you can repeat everything and try changing it like:

<key>PNPVendorID</key>
<string>ADS78 ADS77 ADS76 ADS75 ADS74 ADS73 ADS72</string>

Note I would only try changing ADS75 to ADS7x x="number 6-8" or it may crash

but I haven't had any issues.

I have it fully working in my laptop Samsung X11cv02 with this installer

 

How I can uninstall this or correct it, because I can see in System Preferences -> Sounds -> Input:

Internal Microphone - Built-In

Line In - Audio Line-In port

 

But they are not working and the output has no "Output controls" an I can't control the volume.

I've been using before this the AppleAC97 or the Azalia and at least I have volume control for the output and no input...

SOLVED: I reinstalled: AzaliaAudio.pkg but still no input...

 

I really need a mic...Please Gurus Help!

 

Thanks in advance
