ML 10.8.2 + Nvidia GTS 450 = Need help with HDMI Audio!!!

[toleda]

Hi Toleda,

Thank you again for taking time to review my HDMI dilema.

I have upgraded to 10.8.3 using the combo installer. Everything works great. It is just the HDMI that does not work for my GTX650.

Attached are the files to requested.

New problem; add dsdt/HDAU/layout-id for the ML AppleHDA, edited HDAU:

                Device (HDAU)
                {
                    Name (_ADR, One)  // _ADR: Address
                    Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
                    {
                        Store (Package (0x04)
                            {
                                "layout-id", 
                                Buffer (0x04)
                                {
                                     0x01, 0x00, 0x00, 0x00
                                }, 


                                "hda-gfx", 
                                Buffer (0x0A)
                                {
                                    "onboard-2"
                                }
                            }, Local0)
                        DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                        Return (Local0)
                    }
                }

Hi again Toleda,

I once again want to thank you for your help because everything that you told me worked in a way.

I found my solution and it doesn't include nVidia cards.

I started from scratch. Now have 10.8.2 again.

I returned the GTX650. And got my system working again with the GTS450. But was not satisfied.

I bought a Sapphire Radeon HD 6670 2GB. No injections. No Graphics Enablers. Just exchanged the card and worked without any extra configuration -only the 2gb openCL patch that I had already done for the GTS450-.

Installed the Multibeast ALC8xx ML edition. And edited the DSDT as you instructed.

Fully working ALC892 with HDMI audio.

Attached are the ioreg, dsdt edits, dsdt and the multibeast ML ALC8xx.kext.

The HDMI audio works even if the Azalia audio chip is disabled in BIOS.

The card is not expensive and it delivers better performance than what I was getting with the GTS450. Tested it with X-Plane 10, OpenGL Extensions Viewer, Galaxies and Luxmark. In every test the Radeon performed better. The most notable was X-Plane 10 where the FPS difference was approximately 15 frames in favor of the HD6670 -in the default X-Plane 10 configuration.

Again, I can't thank you enough for taking time to review my information.

Hope this information helps someone else with the same dilema.

Enjoy.
No need to attach AppleHDA.kext as it available to anyone with MultiBeast.
Your 6670 is not properly enabled; the default framebuffer is loading. DVDPlayer and GeekBench among other applications will not work.

After the success I had with 10.8.2, I started from scratch again and installed 10.8.2 again and updated to 10.8.3. I install on an iMac with the drive connected as an external USB drive.

Installed Chimera from Multibeast ML, my edited DSDT and the extensions I use in SLE. Then installed the harddrive again on the Zotac computer.

No configuration or injection needed for the HD6670 2GB. And no patch either. Everything works. Just tried again Luxmark, Galaxies, X-Plane 10 and OpenGL Extension Viewer.

I also just tried Geekbench and DVD Player. Everything is working. If there is another application I should try out please let me know.

I attached the ioreg from 10.8.3., my dsdt.aml and my extensions as reference.

You have luck on your side.

Luck was not what helped me pull it off.

It is because of specialists like you and others around the forums that make our Hackintosh installations easier.

So it is basically thanks to you guys

Maybe what I do different from the guides I have read is that I install on an iMac to an external USB drive. OSX, iLife and updates, while the disk is connected to the iMac via USB.

After that I install Easybeast.

And then I connect the drive to the laptop or desktop via USB again until I sort out all the details like DSDT and SLExtensions.

And only after that, I install the drive internally.

With this method I have installed 10.6.8 on a Thinkpad X300 and a X61s. Both with approximately 95% functionality. And now 10.8.3 on Zotac H61.

So Toleda, when I write that I can't thank you enough for taking time to review my information, I really mean it.

Until the next installation, good day
