Optimized AppleHDA for Realtek ALC 885/889a on Lion - Update

[toleda]

Is it possible to make the front panel work?

What happens in System Preferences/Sound/Output/Internal Speakers when you plug something into the green front port?

Thanks toleda,

nothing happens... it's not detected. It´s working in Windows though.

It´s funny because I´m installing ML in another old mb (P35-DS4) which mounts 889a codec and I have the same problem.

DSDT in both mbs:

            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)
                            {
                                 0x75, 0x03, 0x00, 0x00
                            }, 
                            "PinConfigurations", 
                            Buffer (Zero) {}
                        }, Local0)
                    DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                    Return (Local0)
                }
            }

In P35-DS4 after ML Multibeast installation it is changed to new layout:

                            "layout-id", 
                            Buffer (0x04)
                            {
                                 0x01, 0x00, 0x00, 0x00
                            },

Could an IORegistry save (while connected to front headphones) give you any useful information?

Thanks again

Only if it was working. OS X supports HD Audio; is you front panel AC97?

 

[danif]

Ok.

Focusing in GA-EX58-UD5:

If I use another patched applehda.kext i´m able to use front headphones (rear doesn't work) so here is the ioregistry... hope this provides some clues.

Front panel connectors are described in Case Specs as: USB2x4; eSATAx1; Micx1; HD Audio+AC'97 x1

Thanks

I can see headphones are working in VLC. Attach the working AppleHDA.kext for this IOReg and the non working AppleHDA.kext with an IOReg for the non working kext.

Since the codec does not see the front panel with MB audio, that typically suggests an electrical problem. Verify HD Audio+AC'97: Front panel HD Audio connector is connected to the motherboard audio connector. If you want the gray connector with MB audio, see Mountain Lion: Customizing the Optimized AppleHDA.

 

[danif]

Hey, thanks toleda, you were right.

The problem with both builds was the AC97 connector. I used instead the HDAudio connector and now everything works as expected.

Awesome
Thanks

Hi everybody.
I have problem in configuring the mìc pins of alc885 on linux: can you help me?
more precisely, I'm using an apple macbookair1,1 with linux and the mics are not working (everything else is fine); I put more data here http://unix.stackexchange.com/questions/73044/microphones-on-apple-macbookair1-1
it seems that I'm unable even to get to the appropriate pins and test them, might be a bios corruption issue ?

thanks and best,
N
