Lion HDMI Audio - Part 2a: DSDT Edits/Discrete - AMD/Nvidia

[toleda]

Thanks
WOW!

You AppleHDA.kext is not edited for the 892 audio. Try this:
1. http://www.tonymacx86.com/viewtopic.php?f=16&t=42546.
2. Edit dsdt/HDEF/layout-id: 0x7C, 0x03, 0x00, 0x00
3. Fix permissions and cache
4. Restart and verify 892 on board
5. Make the same GTX 560 edits as before
6. Install 892/560 edited AppleHDA.kext
7. Fix permissions and cache
8. Restart and verify 892 on board and HDMI audio.

Note: it is possible on reboot (step 8) you may have a black screen caused by Nvidia HDMI audio and 10.7.2 and perhaps .3. Reboot with GraphicsEnabler=No flag and reinstall the 892 edited AppleHDA.kext.

Regarding AppleHDA binary edits
"92 08 ec 10" address is already in AppleHDA binary
edit "14 00 de 10" to "16 00 de 10" is correct for GTX 560 in AppleHDA binary.
edit "de 10 ea 0b" to "de 10 0c 0e" is correct for GTX 560 in AppleHDAController binary.

What display is connected?
Suggest new 560 patches on a fresh 892 AppleHDA.

Display connected is a Panasonic 1080p HDTV.

-New 892.
-Changed binaries

Almost alive...
Only one channel of audio comes through

Have any ideas?

Edit: Maybe its that theres no bass at all or something. Songs sound crazy thin.

No idea. What happens in Audio MIDI Setup/Audio Devices/HDMI/Configure Speakers?

Ok so...
Anything lower than 70hz is cutting off, and anything above 17khz is also gone.

Maybe you have some knowledge of this?
