Hi, can someone help me with my onboard audio and hdmi audio from my gtx480 graphic card issue. I've managed to install Mountain Lion with the update and 'I think' all is working well. What I read is that I CANNOT use the audio via hdmi from my graphic card until I have the onboard audio working. I have used AD2000b.kext for my motherboard from this site but still no audio option. I then installed the VoodoHD and I get audio options but cannot use VoodoHD as it will not allow me to use the gtx480 hdmi sound.


So please could someone shed some light where im going wrong or modify my DSDT.aml to work my onboard audio and enable my gtx480 hdmi sound as that would be much appreciated and please could someone just check my dsdt.aml to ensure it's ok.




System Spec


Asus Rampage II Extreme

i7 920 d0 stock speed

GTX 480


I've had to rar the file as it would not allow me to upload due to size limit.
