Hi Toleda, you've had some time to look at my DSDT to activate the HDMI on the second graphics card?
because when I connect the TV to the first card where there is also connected to the monitor, the temperature rises highly…!
But i think its normal…!
I tried to only understand that the second card is: GP7… just...

Thank's in advance!

Lucke.

There is a problem with the HDMI audio edits. Attached is a laptop HD4000 HDMI audio editing kit. Required edits:
1. HDEF "layout-id", edit: 0x01, 0x00, 0x00, 0x00 to your layout-id
2. GFX0 "AAPL,ig-platform-id", edit: 0x01, 0x00, 0x66, 0x01 (01 Capri has an HDMI connector on Port 0x5, 03 Capri does not)

If 01 Capri does not work or HDMI video is not on Port 0x5, Edit 03 Capri for correct HDMI connector port.

Work fine. Thanks a lot.
I was stupid, because i think the problem is in the bad patch AppleHDA or wrong device-id.
Now i try to add this fix to my dsdt, because I prefer use vanilla kexts.

Another question ¿ can you add support ALC269VC to you AppleHDA8Series.sh?

I love patch AppleHDA kext on-the-fly with Clover boot loader, because my S/L/E is 98% vanilla (only have AppleHDA patched, and now AppleFramebuferCapri). The extra kext i need are in EFI/CLOVER/kexts/10.9.
I have linux dumps, ioregs, pinconfig, verbit... to share it, and I have time to test it.

Tanks in advance.
