Hello,

 

I 've got some problems to get my soundmax running.

 

I made the changes to AppleAC97CodecAD198xkext (Add ads70) but now I can't load it with kextload.

 

I've typed:

 

kextload -t /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97CodecAD198x.kext

 

This was my reply:

 

kernel extension /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97CodecAD198x.kext has problems:

Authentication failures:

{

"File owner/permissions are incorrect" = (

"/System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97CodecAD198x.kext"

"/System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97CodecAD198x.kext/Contents/Info.plist"

"/System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97CodecAD198x.kext/Contents"

"/System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97CodecAD198x.kext/Contents/MacOS/AppleAC97CodecAD198x"

"/System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97CodecAD198x.kext/Contents/MacOS"

)

}

 

What can I do now? Please help if you can. Thanx.

try this:

 

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

 

and repair permissions using disk utility which can be found in applications->utilities

 

then reboot

Yo, that worked and the .kext loads fine.

I can now set the channels but I still can't hear any sound.

 

Yesterday I went on ebay and bought a 5.1 USB audio stick for $6.99.

I think this will work.

 

Thx again............rze

Please help!! I have a soundmax 1980 on an ASUS K8V-X and now after adding ADS70 to the codec kext within the ac97 kext it says the via kext is not valid. What a mouthful but I really needed to say it.

 

I've tried everything and now my kext isn't valid. I've repaired disk permissions used the rm on extensions.kextcache and mkext and still nothing. Yea I'm running on a VIA so I checked the via kext the and the ven id and dev id is exactly the same as mine. So I didn't modify it and moved on to the codec kext and tried that one and changed one to ADS70 as my card is from looking at one of the data sheets.

 

Please I really wanna get my audio setup and working. I don't mind occasional glitches as long as it's not every minute or so. Everything works except the stupid audio. TIA and I appreciate any help.

I just wanted to give a big thanks for all the advice in this thread.

 

I finally got my onboard Soundmax audio working, however, I only had left channel audio. I needed to download the fixed stereo AppleAC97Audio.kext from this thread, then hack the info.plist from the AppleAC97CodecAD198x.kext to get stereo working.

 

For further info, my motherboard is an ASUS K8V-SE Deluxe with the Soundmax ADS1980 chip and requires the AppleAC97AudioVIA.kext to function.

 

The AppleAC97AudioVIA.kext already had the correct vendor and device string, so all I had to do was add ADS70 to the AppleAC97CodecAD198x.kext, purge the cache, repair permissions, reboot and voila - stereo sound!

 

Thanks again to all the gurus for all their help.

After much searching, reading and trying I finally figured out that there appears to be a dependancy between AppleAC97Audio.kext and in my case, AppleAC97CodecAD198x.kext.

 

<string>ADS70 ADS75 ADS74 ADS73 ADS72</string> <-------- Added ADS70

You're the man! :D This tweak helped me get audio working on a Dell Dementia 4700, running JaS 10.4.8 installation. Unfortunately, the built-in Intel Pro/100 VE fast ethernet is still a mystery despite all the useful tweaking info around for it.

I have an AD1888 chip paired with ICH5. The PNPVendorID on the AD1888 seems to be causing problems in my case. Anyone seen this before?

After much searching, reading and trying I finally figured out that there appears to be a dependancy between AppleAC97Audio.kext and in my case, AppleAC97CodecAD198x.kext. It seems you need to have the Vendor and Device IDs set correctly in both. I started in just trying to change AppleAC97CodecAD198x.kext. It would load with kextload but nothing worked.

 

First find the Vendor and Device ID by doing Start>Run> DXdiag in Windows. Now boot into OS X and then modify the Info.plist file here: /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97AudioIntelICH.kext/Contents/Info.plist

 

Remember your Vendor and Device ID most likely will be different.

 

<key>ICH6 AC97 Audio</key>

 

<dict>

<key>CFBundleIdentifier</key>

<string>com.apple.driver.AppleAC97AudioIntelICH</string>

<key>ICH Type</key>

<integer>6</integer>

<key>IOClass</key>

<string>AppleAC97AudioIntelICH</string>

<key>IOPCIPrimaryMatch</key>

<string>0x25A68086</string> <--------Added Correct Dev=25A6 Ven=8086

<key>IOProbeScore</key>

<integer>10000</integer>

<key>IOProviderClass</key>

<string>IOPCIDevice</string>

</dict>

 

Also, I first changed AppleAC97CodecAD198x.kext Info.plist but didn't have any effect. After I made the changes above sound starting working immediately.

 

Below are the changes made to AppleAC97CodecAD198x.kext Info.plist:

 

<dict>

 

<key>CFBundleIdentifier</key>

<string>com.apple.driver.AppleAC97CodecAD198x</string>

<key>IOClass</key>

<string>AppleAC97CodecAD198x</string>

<key>IOProbeScore</key>

<integer>10000</integer>

<key>IOProviderClass</key>

<string>IOAC97CodecDevice</string>

<key>PNPVendorID</key>

<string>ADS70 ADS75 ADS74 ADS73 ADS72</string> <-------- Added ADS70

</dict>

 

Got the ADS70 code from looking at the mother board manual ADI AD1980 AC'97 codec and searched for the chip data sheet on line. I found this near the end of the chip data sheet:

 

7Ch Vendor ID1 F7 F6 F5 F4 F3 F2 F1 F0 S7 S6 S5 S4 S3 S2 S1 S0 4144h <--41=ascii A, 44= D

 

7Eh Vendor ID2T7 T6 T5 T4 T3 T2 T1 T0 REV7REV6 REV5 REV4 REV3 REV2 5370h b]<--53=S[/b]

 

It looks like both Plist files were needed to be modified with the right codes, funny thing is that the Vendor code from the DXdiag in Windows says it's an Intel = 8086 and the data sheet and MB manual says ADS = Analog Devices. I needed to add the Intel Device/Vendor ID for AppleAC97AudioIntelICH.kext Info.plist and the Analog Devices Vendor/Device ID for AppleAC97CodecAD198x.kext Info.plist.

 

After doing a ioreg -l in terminal window I found this in the listing that confirms that both might be needed to make this work.

 

AppleAC97AudioIntelICH <class AppleAC97AudioIntelICH, !registered, !matched, active, busy 0, r$

| | | "ICH Type" = 6

| | | "IOClass" = "AppleAC97AudioIntelICH"

| | | "IOPCIPrimaryMatch" = "0x25A68086" <------Found the change I made here

| | | "IOProbeScore" = 10000

| | | "Power Management private data" = "{ this object = 03a06c00, interested driver = 03a06c00, dr$

| | | "IOMatchCategory" = "IODefaultMatchCategory"

| | | "IOProviderClass" = "IOPCIDevice"

| | | "Hardware Name" = "Intel ICH6"

| | | }

| | |

| | | {

| | | "PNPVendorID" = "ADS70"

| | | }

| | |

| | +-o AppleAC97CodecAD198x <class AppleAC97CodecAD198x, registered, matched, active, busy 0, ret$

| | | {

| | | "IOMatchCategory" = "IODefaultMatchCategory"

| | | "Hardware Name" = "ADS70" <-----Found the change I made here

| | | "IOClass" = "AppleAC97CodecAD198x"

| | | "PNPVendorID" = "ADS70 ADS75 ADS74 ADS73 ADS72"

| | | "IOProviderClass" = "IOAC97CodecDevice"

| | | "CFBundleIdentifier" = "com.apple.driver.AppleAC97CodecAD198x"

| | | "IOProbeScore" = 10000

 

Needed to kextload /path to .kext to load/AppleAC97AudioIntelICH.kext and after that audio was working great! Might be that some of us have been doing one or the other just happened to have the right Vendor/Device ID in the other file and got it to work without realizing that both were needed...

 

Hope this helps someone, Kyklops @-)

 

I dunno if it matters to anyone but i first installed this soundchip way back at Leo4All v3 and used the default AC97 driver. When installing 10.5.6, i went back to it and installed it and it worked like magic.
