Mountain Lion - Realtek 889a not working after trying many methods!

[ahopeinhell12]

I recently installed Mountain Lion, and for 4 days straight I've been trying to get my onboard audio to work. I've got a GA-Z68X-UD3H-B3 board with ALC889a/885 on-board audio. I've tried at least 3 different DSDT mods, Toleda's kext, etc.

After setting up a custom DSDT, my System Information->Audio looks like this:

[B]Intel High Definition Audio:[/B]


  Audio ID:    12


[B]S/PDIF Optical Digital Audio Output:[/B]


  Connection:    Internal


[B]Line Output:[/B]


  Connection:    1/8-Inch Jack


[B]External Microphone / iPhone Headset:[/B]

  Connection:    Optical

My HDEF currently is layout 12 and looks as follows:

            Device (HDEF)
            {
                Name (_ADR, 0x001B0000)
                Method (_PRW, 0, NotSerialized)
                {
                    Return (Package (0x02)
                    {
                        0x0D, 
                        0x05
                    })
                }
                Method (_DSM, 4, NotSerialized)
                {
                    Store (Package (0x04)
                        {
                            "layout-id", 
                            Buffer (0x04)
                            {
                                0x0C, 0x00, 0x00, 0x00
                            }, 
                            "PinConfigurations", 
                            Buffer (Zero) {}
                        }, Local0)
                    DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                    Return (Local0)
                }
            }

Could you please suggest kexts and/or DSDT edits for my setup?

Thank you for your time

I also have 889a. This is what worked in the end.

Install these two kexts with kext utility and (hopefully) voila!

I installed the kexts with Kext Wizard, and rebooted with no result. I now realize my real problem: that the ALC885HDA.kext isn't loading. I repaired S/L/E permissions using Kext Wizard, so that shouldn't be a problem. I don't know what else would be interfering, any idea?

So I solved my problem.. it turns out the GA-Z68X-UD3H-B3 uses ALC889 and ALC889a.
