Video memory - off topic, i don't know
dsdt - compiles in DSDTSE
6950 - See AppleHDAController Binary Edit in Lion HDMI Audio - Part 3a: Kext Edits - AMD

Hi, I'd like to know if it's possible to have HDMI audio with the AppleHDA edits on dual graphics? *two gtx 470's* I followed the guide and patched everything as instructed but can only get the HDMI audio controller on the first video card to initialize, both are recognized in IOregistry and I'm pretty sure it isn't my DSDT edits. Also, two "HDMI/DisplayPort Output" show in System Information, but only the primary card is initializing.
System is Mountain Lion.

ids used:
HDAU Device_id: de 10 e5 0b (AppleHDAController)

IOHDACodecVendorID Device_id: 10 00 de 10 (AppleHDA)

It looks like you have HDMI audio on one card (PEGP@2). The other card has no HDMI device/display connected. Is that the plan?

Yes, there's nothing connected to the secondary card.
