Hi toleda,
I have read the guide but i'm not sure. I have a GA-B75N mainboard with a i3 3225 HD4000 graphics. I can see that my board does not have a DSDT in the database. I have read that I need a DSDT to get the HDMI audio to work.
Under the Requirements I have :
1. Intel
1a. Ivy Bridge 7 Series motherboards - Z77, H77, B75
No problem
2. OS X
2a. Mountain Lion - 10.8 and newer
No problem
3. dsdt - no compile errors
3a. No dsdt, see [GUIDE] Creating your own DSDT for most boards
Not sure from this point on!! Sorry I know it sound very lame!
Any help here would be nice... So far I have not install anything, just getting all the info before I start.
Thanks,
Ross
