Thanks for your fast reply. I installed the Kext and there are some HDMI and some Green Rear and so on outputs and one input. No one from them is working. My sound card uses the AD1988B Codec. In the internet was standing, that I need to change something in the Voodoo Kext, that my sound card with the special Codec will work. My Kext for the AD1988B Codec was working perfect, until I upgraded my graphics card to an graphics card with an HDMI port.
I hope someone can help me!
Thanks in advance!
