Gracias iFIRE por responder. Tengo otro problema que para mi es mas importante que lo del audio por HDMI; se trata del brillo, siempre que reinicio el brillo se resetea y tambien cuando el equipo despierta, lo hace con el brillo al máximo, pareciera ser que mas del 100% del que se puede configurar con el slider de preferencias. He buscado por todos lados alguna solución, pero no he tenido suerte. Quizá sea problema del DSDT pero no estoy seguro.
Tienes alguna idea de como solucionar esto?

Just wanted to say that this laptop doesn't have LaCie USB 3.0 and therefore, you don't need PXHCD. It has intel USB 3.0 which doesn't work with USB 2.0 devices under os x.
To fix this, delete the AppleUSBXHCI.kext in IOUSBFamily.kext. This will make the port work with both USB 2.0 and 3.0 devices but at USB 2.0 speeds.

Hi iFIRE, aun estoy tratando de activar el audio por HDMI. Adjunto los archivos que me pediste. Espero puedas ayudarme. Muchas gracias.

Update: Is working now :)

Sólo tuve que editar el framebuffer. Gracias de todos modos

Well, i have more time now to test an installation. Lets resume what i got to the moment:

1.- I've actually managed to boot correctly the usb installer and to install ML on my Inspiron 14z 5423. I've used GenericUSB3 kext and VoodooPS2 for getting usb boot and Mouse/Keyboard working.
2.- On 10.8, Intel HD4000 Graphics load correctly using an EFI-String
7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31
3.- I've updated to 10.8.3. Since that, i cannot boot on "Normal" mode. Just on Safe Mode. (On Normal Mode the last line shows an error about Sandbox deny mach-lookup com.apple.coresymbolicationd)
4.- Also, i've run ssdtPRGen and configured org.chameleon.boot.plist to drop SSDT. I'm using a MBP 9.2 smbios.
5.- I have not yet edited or patched my DSDT with something in particular. Should I patch to consider anything?
6.- I don't have sound, neither Wifi, or Ethernet working. Webcam works normally. Bluetooth seems to work, but i haven't tested it yet.
7.- My laptop came with a hybrid graphics set (HD4000/Ati HD 7570M). Is there a way to get both working, or at least, to shut down the Ati, like in Linux, for example?

Thanks for help.
