Lion HDMI Audio - Part 3b: Kext Edits - Nvidia

[munkicloud]

1. "The selected device has no output controls"
Indicates the HDMI device (ex., DTR-40.2) controls volume, mute, etc., Lion does not.

I guess there's no way to change this, is there?

Everything looks good in your dsdt and ioreg. What are the sound assertions in console? Have to find a way to get onboard audio working (with out the enabler) to get hdmi audio.

I am in the same situation. I have, thanks to toleda, been able to extract a DSDT file now that compiles successfully without any mod's and follow the instructions with no problems (I have gone through the entire procedure 3 times now with no problems). The only thing that is not as excepted in the instructions is that my device address is 0x00060000 instead of 1 or 3 as per the instructions.

When I get to the end of the process I have no output device(s) in the Sound panel except my USB Audio.

I assume I need to get the onboard audio working to get HDMI at this point - does anyone have any hints/suggestions for my MB and graphics card?


TIA,

Frank

rajeewa,

Where I can find AppleHDAController

It is inside the AppleHDA.kext - right click on AppleHDA.kext in your finder window and select show contents.

I added following section to my (Nvidia GT 520) dsdt.aml
Store (Package (0x06)
{
"@0,connector-type",
Buffer (0x04)
{
0x00, 0x08, 0x00, 0x00
},

"@1,connector-type",
Buffer (0x04)
{
0x00, 0x08, 0x00, 0x00
},

"hda-gfx",
Buffer (0x0A)
{
"onboard-1"
}
}, Local0)
it compiles ok.
But I can't find IOHDACodecDevice@0. in IOregistry instead i can find IOHDACodecDevice@1B,2

What did I do wrong..Any help much appreciated.

Wonderful ..working really Good ...
No volume control but after all its a Bus ..

Hard work editing the Dsdt first ..
Ive have a question about it ..
"I wasnt able to name device as PEPG but i need to keep POP5 in Dsdt .. "

    Device (P0P5)
            {
                Name (_ADR, 0x00050000)
                Name (_PRW, Package (0x02)
                {
                    0x09, 
                    0x05
                })
                Device (GFX0)
                {
                    Name (_ADR, Zero)
                    Name (_SUN, One)
                    Method (_DSM, 4, NotSerialized)
                    ..........

I clearly Recommand to everybody at part 3 to Edit AppleHda Completely before to install and reboot
Editing only AppleHdaController Give me Nice Kernel panic when the display with Hdmi was connect .
Maybe something useful for other to edit AppleHda :
Copy AppleHDA to desktop
Open HexEdit

The first file to edit is there
1/ Open : AppleHDA / contents / Plugins / AppleHdaController.kext/Contents/MacOs/AppleHdaController

The Second One is there
2/ Open : AppleHDA / Contents / MacOs / AppleHDA


-So is there a way that i edit also AppleHda to make it recognize my internal audio device ??

Congratulations.
Your monitor has volume control.
On board audio; what is the device_id (IOReg/HDEF/AppleHDAController/CodecList)?
