How do I get my DSDT? What do I need to do to edit it properly? Help would be much appreciated... I would rather just get rid of my HD4000 kexts but that obviously didn't work...
First off, I'm having a little difficulty following your post - #1 is the IGPU in bios, #2 is the DSDT edit - I'm assuming you've just got the numbers the wrong way round (if I'm misunderstanding then let me know).
Are you sure you deleted all relevant intel kexts? As well as deleting AppleIntelHD4000*.kext , try deleting AppleIntelHDGraphics*.kext (AppleIntelHDGraphics, AppleIntelHDGraphicsFB).
I can help you with DSDT editing, but this is probably not the thread for it. A basic overview is that you will have to extract your normal, unedited, DSDT first, then apply a number of automated patches with macIASL. To avoid the problem, you simply do not apply the HDMI audio patch when editing the DSDT.
The best solution I have found and the one that I currently run is a bit more complex but solves the issues. It relies on using the Ultra Fast motherboard boot option and the clover bootloader, which allows for a native UEFI boot rather than emulated BIOS. With a compatible graphics card, this means that you can use the GPU output to display the boot content, even if IGPU is set to primary. This solves all the problems - you can use HDMI audio, select stuff at the boot screen, not have to delete any kexts, have airplay mirroring etc. As an added bonus, boots are generally faster (Windows 8 will boot in about 1-2 seconds on my setup, OSX 3-10 depending on settings). If you are up for trying, let me know and I'll do my best to help you out.
