I've tried many of the methods listed in the forum (ALCInject, AppleHDA, HDAEnabler, HDAudio, HDA_885_889A_for_BOOT-132_BETA_V4, HDA_995_889A_BETA_V5, ...) for getting the ALC885 chipset working on this motherboard. At this point, all I have is the following in System Profiler, nothing listed in the System Preferences -> Sound menu, and no sound working...

Intel High Definition Audio:

Device ID: 0x80863A3E
Audio ID: 888

Any help is appreciated...

I actually have the exact same board as you. I got sound to work by using the VoodooHDA driver.

Download it from here: http://code.google.com/p/voodoohda/downloads/list

For an easy installation, simply copy it to your /System/Library/Extensions folder, chown -R root:wheel VoodooHDA.kext, chmod -R 755 VoodooHDA.kext, remove the Extensions.mkext (extensions cache) and reboot. Please note that I got this working without patching the AppleHDA.kext, or using HDAEnabler, or ACLInjector. You should be able to drop it right in without changing anything. In fact I would revert back to the stock OS kexts before installing, and remove any other additional kexts that might interfere.

For a more advanced installation (I prefer not to tamper with the OS kexts, or install kexts to the OS X partition), use Chameleon and copy the kext and dependencies to the /Extra/Extensions directory.

For more information on this check out this link: http://forum.voodooprojects.org/index.php/topic,155.0.html

Let me know if it works for you, if not, I can probably help troubleshoot your issues.

Actually, depending on your exact setup, I could send you my Chameleon USB image. You can simply copy it to a usb thumb drive, and set your BIOS to boot of the USB drive. It has all of the necessary kexts for our board, etc.

Robert, this worked perfectly -- thanks a ton.

For anyone else out there using the DFI LP JR P45-T2RS...

I did a fresh vanilla 10.5 install using a modified Boot-132 CDROM with the following kexts, upgraded using the 10.5.7 combo, and installed NVDarwin 1.2.5 for my graphics card.

ACPIPS2Nub.kext
AppleACPIPS2Nub.kext
AppleDecrypt.kext
ApplePS2Controller.kext
AppleSMBIOSEFI.kext
IntelCPUPMDisabler.kext
LegacyAppleAHCIPort.kext
LegacyAppleIntelPIIXATA.kext
LegacyIOAHCIBlockStorage.kext
NVinject.kext
OpenHaltRestart.kext
SMBIOSEnabler.kext
VoodooHDA.kext
dsmos.kext

I'm not sure all these are necessary because they are an amalgamation of various attempts to get this board fully working. Robert, I'm curious how this lines up with what you use?

FYI, to create a bootable ISO here's the command:

hdiutil makehybrid -o ~/Desktop/BOOTUP.iso ~/Desktop/BOOTUP -iso -eltorito-boot ~/Desktop/BOOTUP/ISOLINUX.BIN -no-emul-boot

hdiutil burn ~/Desktop/BOOTUP.iso

Finally, the sound didn't work until I copied the VoodooHDA.kext into the /System/Library/Extensions folder and updated the ownership, so it's probably unnecessary on the CD that I use.

Hi,
I had the JR P45-T2RS. However the audio is not working when using SPDIF.
Cracking sound.
Any idea how to make the SPDIF works?
