I have Realtek ALC888 codec and my System Preferences shows LineOut and LineIn but my Mic, Headphone is not working, only external speakers are working. Also my System Profiler -> Audio (Built-in) shows no Built-in Audio device written in it. I tried all types of combination of AppleHDA.kext, Taruga Patch, ALCInject.kext and HDAEnabler.kext but no success.

What should I do to make it working and also get details of Built-in Audio in my System Profiler?

Please, please, please help...

I am attaching linux codec dump which I got after booting from Ubuntu Live CD. In Linux the sound worked perfectly fine and also showed all audio hardware details. I used AppleHDA patch with the same codec dump but the problems did'nt resolved. Please help

Here is my Linux Codec Dump

No help from the big guys?

This one worked for me.

What motherboard are you using?

You don't need ALCinject.kext or I don't think you would need it.
Post your AppleHDA.kext and I will try to see what pins go where.

Here is my AppleHDA.kext which I am using currently.

My motherboard is based on an X38 with an ALC888 Dolby Digital sound chip.

Any news about sound input?
I have ALC861, same problem, the sound output is fine. but the input doesn't work.

Hi Guys!

I know it's been a while since you've resolved the Realtek ALC888 problems, as i can see in MacNuttys signature.

I've stalled out on this issue. I have a codec dump from Suse Live CD. I tried Tarugas HDA Patcher, which reports:



* Patching AppleHDA.kext to 0x10ec0888 Done
* Checking AppleHDA for patch Done
0001f4a0 cmpl $0x10ec0888,%eax
00020584 cmpl $0x10ec0888,%eax
* Checking for SPDIF Out Detected
* Checking for SPDIF In Detected
* Using the following nodes in pathmap

Back Mic: 9 34 24
Line In : 8 35 26
Speaker : 20 12 2
Headphone: 27 38 37
Spdif In : 10 31
Spdif Out: 30 6

* Copying new config to destination Done
* Repairing Permissions Done
* Deleting Extensions Cache Done

** Done patching - You can reboot now **

After reboot: no sound :-(

I've deleted every other audio kext, nothing will get it to work...

I think I'm missing something and I'd be happy to get a hint in the right direction.

My codec dump and the HDA.kext are attached

Thanks for the help....

Just wanted to share this. Got my ALC888 working with the attached *.pkg

Even optical out works. About this Mac shows: No Built-in Audio ???

Any hints?
