Grandflash's kext goes with a DSDT edit ... you have to update your DSDT to make it work !

If you don't know how to do so, you can read "DSDT edit for dummies" made by Silencer.

Useful applications are DSDTse (to extract your DSDT, but it is a buggy text editor ..), Fraise (good text editor) and iaslme (to compile to .aml and to de compile in .dsl which is text)

I think the DSDT edit you have to do is to replace "Device(HDEF)" with this one but I am not sure ...

Code: Select all

Device (HDEF)
            {
                Name (_ADR, 0x001B0000)
                Name (_S3D, 0x03)
                Name (RID, Zero)
                Name (_PRW, Package (0x02)
                {
                    0x0D, 
                    0x04
                })
                Method (_PSW, 1, NotSerialized)
                {
                    Noop
                }

                Method (_DSM, 4, NotSerialized)
                {
                    Store (Package (0x08)
                        {
                            "layout-id", 
                            Buffer (0x04)
                            {
                                0x0A, 0x00, 0x00, 0x00
                            }, 

                            "subsystem-id", 
                            Buffer (0x04)
                            {
                                0xA0, 0x00, 0x00, 0x00
                            }, 

                            "subsystem-vendor-id", 
                            Buffer (0x04)
                            {
                                0x6B, 0x10, 0x00, 0x00
                            }, 

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

Thanks for the tip. Using DSDTse, it looks like the current DSDT entry for Device HDEF is 970 lines in length. So, I am replacing those 970 lines with these couple of dozen? Is the section to be replaced starting from the line with HDEF up until the next 'Device' section starts?

Edit: Finally got sound working using the AzaliaTurboTP1984.kext from the below link. There is another AppleHDA.kext there I will try tomorrow to get audio line out working.

Here's what's working on this build, and what is not. Any suggestions appreciated;

Working;
Sound
QE
Speedstep (I think, based on temperatures)
Airport WiFi
Battery Guage
Sleep
USB
Thinklight
Apple Keyboard, all keys (except brightness)
External USB Mouse
Advanced Minidock
VGA Output on dock

Not Working;
DVI Output on dock
Bluetooth
Brightness

I installed the AppleHDA.kext and modified the EFI per the instructions by priitv8 in the below thread. I now have full working sound, including SPDIF output through the Advanced Mini Dock. Still looking for pointers on the non-working items above.

I have attempted to follow your procedure listed, as well as retrace your footsteps here. Yet I cannot obtain the same results on my R61e. Which DSDT were you using ?
