[toleda]

You still have the audio enabler installed. When the line Credits in HDEF disappears, you'll know its gone.

See if this solves your black screen problem. If you have the 889 and 430, no kext editing is required.

Same result on 10.7.1 AppleHDA.kext (2.1.1f12), black screen on alc892+nvidia patch.

For the GTX570 nvidia patch alone i used AppleHDA.kext 10.7.2 (2.1.3f7)

I'm out of ideas for now, i guess it's something related to the pathMaps or so (platforms.xml), as you said.

The assertion errors goes along these lines:
Sound assertion "0 == pathMap_aDriverInstance" failed in AppleHDA sourcecache...

This problem has spread to all of my machines. I have not figured out what has changed in 10.7.2 . In the meantime, I prepared a work around based on AppleHDA_v1.7.9. It is patched for the 892. Apply this edit for the 570 to AppleHDA binary:
Find: 14 00 de 10
Replace: 18 00 de 10 (4 times)

Just tried it and no luck unfortunately. Tried doing a few cold boots and unplugging the power cord but nothing, only HDMI audio worked well, tried internal speaker and any other output line but nothing on this board.
