GA-B75N - Intel 3225 HD 4000 HDMI Audio

[Yannich]

As i told you in my last comment the patched kext is available in multibeast.

DSDT edits are available in this link > http://www.tonymacx86.com/graphics/53925-qe-ci-hd3000-series-7-mainboards-2.html#post460625

Let me know if you need help.

First of all, thank you for your effort
But i don't know how to edit my DSDT.aml in DSDT editor... i can open the file with the help of another mac, my usb stick has a DSDT, but without any "device imei" :
i also tried to install the graphics kext with multibeast on the usb stick, but it causes again the error
if i delete the DSDT, i can get into my installation, but then , nearly to the end of installing 10.8.3 it causes also an error...

Extract a DSDT using DSDT Editor tool and save it as .dsl format (4th option under file tab) compress it and attach.

I have added the patch to the attached DSDT try it.

Not sure the DSDT that you have attached is extracted from a UEFI BIOS. It has all the edits already. Are you using someone else DSDT?

Just to make sure you are not using someone else DSDT can you do a fresh installation OSX or extract a DSDT on windows using DSDT Editor and attach it?

Recreate the Unibeast drive and make sure there is no DSDT in Extra folder of unibeast drive. Extra folder in unibeast drive is hidden you may consider using the tool "ShowAllFiles".

Make sure BIOS are set as per > http://www.tonymacx86.com/99-quick-guide-configuring-uefi-gigabyte-s-7-series-lga-1155-boards.html

Disable - Vt-d

Let me know if you need help with the multibeast settings.

sorry for the late answer
okay it seems to start normal without issues, but very slowly for an ssd my old hackintosh is faster booting on a hdd, very strange.
when mountain lion is up, the resolution is set to 1024x768, how do i manage this to get the native 1080p resolution ?
I just purchased an old 8800gt 512mb btw, it should word "out of the box", right ?
Later i want to get a gtx 660 or something on this level

Cybermole, I owe you a drink. I can't tell you how many times I've tried to get hdmi audio working with this motherboard and your procedure worked the very first time. Thanks!
