Hello,

Any chance that anyone saw anything in the package I added that explains why core audio crashes when I try to airplay?

I have HDMI Audio, I have both video cards identified...

The problem follows NVIDIA video cards - if I use my HD6850 I don't have any problem at all with Airplay but that card is dying (I get vector tearing in games)...

Just not sure what else I am missing here and I am completely open to your input.

Thanks,

The attached IOReg is not from the attached dsdt. DCPIManager/Misc/bdmesg tells you where the dsdt is loading.

Thank you.

Ok - So here is the IOREG from how I am sitting @ the moment. Same scenario as described previously - I am able to boot without DSDT and have HDMI audio. However no airplay.

Thanks again.

Same, are you using a HDMI audio ssdt?

There is likely a DP port instead of 2 HDMI on your 670. DVI display will never show as HDMI. The receiver is showing as DVI. Need an HDMI display device.

Hi Toleda,
Thank you for reming me to check the ports on my GTX670. I found it has some problems to output the HDMI audio even in win7.
After i changed it with a GTX680, the HDMI port works!! Thank you for your contribution to the HDMI audio!

This is why you are a genius Toleda

I am in-fact using your SSDT-1.aml file which appears to enabling the HDMI audio. Attached here are the SSDT files I am using.

I made a discovery today - although I am able to see QE/QI features like menu transparency and screensavers (As well as WoW playing) video is causing a full system lockup in-browser and out of browser (including youtube).

I will try to remove the SSDT and leave the DSDT and see what I get.

Let me know if you have more ideas...

Missed this in Post #1, ML: UEFI HDMI audio, no dsdt edits
Notes

1. Do do not use this method if you already have HDMI audio
