[Easy Guide] ML: UEFI HDMI Audio

[toleda]

I repeated the steps and installed the DSDT in /Extra folder. But same things

Big difference.
Remove this injection from the dsdt, edit Package to 0x04.

                        "AAPL,ig-platform-id", 
                        Buffer (0x04)
                        {
                            0x0A, 0x00, 0x66, 0x01
                        },

Reply with edited dsdt and IOReg.

new IOReg and DSDT

AppleIntelSNBGraphicsFB.kext is not loading. Has the kext been modified? Suggest running the 10.8.4 Combo Update to ensure the native kext is installed.

 

[JunkLee]

AppleIntelSNBGraphicsFB.kext without modifications.

I installed 10.8.4 Combo Update, but nothing...

Do you have another suggestion?

Add this to the dsdt in the place where you removed AAPL,ig-platform-id and edit Package to (0x06)

                            "device-id", 
                            Buffer (0x04)
                            {
                                0x26, 0x01, 0x00, 0x00
                            },

PROGRESS!

Now HD 3000 detected in System Information. But showing 512Mb and I have 64Mb in Bios, if I change to 512Mb in the Bios, got Kernel Panic.

HDMI Audio on HD 3000 and GTX650 works.

Don't touch the BIOS setting. OS X decides on the amount of graphics memory based on the amount of RAM on the motherboard (i.e., 8 GB or more = HD3000/512 M graphics).

OK I understand!

Good job!

HDMI A/V working on HD3000 and GTX650 TI !

Thank you so much for all your work! Thank you for your patience!

Hi Toleda
This new guide seems much easier than anything before.
I have a GA-B75M-D3H with a i5 3350P.
This chip does not have HD video.
I do have a GT 640 from Galaxy.
Will this CPU even work for HDMI ?

It does work,I should use first patch right ?

I did a search on 3350P but page numbers do not line up with posts.
The threads were quite long with many participants.
They predate your new method anyway.

Since the 3350P does not have video,airplay of any kind will not work ?

GT 640 HDMI audio will work. Yes. Airplay will not work.
