Not open for further replies.
here are the 'Problem Reporting' files you requested.. layout-ID is set to 8 now ( wich is the one my patch uses ) but still no audio device and dpcimanager shows me 2 audio devices.. why?

Layout-id 8 is very unlikely.
See ACPI patching guide for how to check your AppleHDA for layout-id.

I double checked this time and it was layout-id 3 but I still don't have any audio device... I checket with linux to see if I'm patching the right audio codec and it's ok... I don't understand what I'm doing wrong
 
What I've done so far:
- using patched applehda CX20756 (I used linux to detect my codec id) (patched with apple hda patcher) (kext is loading)
- layout-id 3 DSDT patch (I checked applehda.kext and layout-id 3 the one is requested)
- HPET/IQR DSDT patch

My problem:
- No audio device detected.

I used this audio patcher just for report.txt (http://www.insanelymac.com/forum/files/file/496-applehda-patcher)

Hardware info:
- Conexant CX20756 (14f1:5114) Rev.(00100100)
- Controller 8086:9c20 (sub-ven:1179:f920)
- Driver: AppleHDA.kext

Found "Device (HDEF)" in DSDT.aml
Found "Device (B0D3)" in DSDT.aml, you should rename it as "Device (HDAU)" for a working audio! - I can't boot if I do this
Found property "layout-id" in DSDT.aml
Found 1 occurennces of "layout-id" in ioreg, not sure what's will be for HDEF..
Found supported "layout-id = 3" in ioreg: be sure that respect your audio connectors
Found more than one "Device (HDAU/B0D3)" inside your ACPI tables. Please remove those excessive!

"AFGLowPowerState" in AppleHDAHardwareConfigDriver.kext Info.plist is nonsense.
 
"AFGLowPowerState" in AppleHDAHardwareConfigDriver.kext Info.plist is nonsense.

Then my kext is the problem? I can't find any working patched applehda for CX20756, my audio is fine with voodohda but I need to use patched applehda for better quality

You should use Mirone's AppleHDA patcher. See FAQ for links.
 
I used that man, and you said "AFGLowPowerState" in AppleHDAHardwareConfigDriver.kext Info.plist is nonsense.

For you to investigate. Look in the Info.plist. AGFLowPowerState should be <03 00 00 00>, or not specified.
 
if i use this patcher http://www.insanelymac.com/forum/files/file/496-applehda-patcher ( wich is using mirone's patches ) AGFLowPowerState is not specified but still I do not have any audio device

aDummyHDA.kext + clover patches + dsdt patches method is giving me the same results.. what is going on here? can you check again the files i sent you a few posts up?
