try using EFI strings or patch your dsdt

works with stock AppleHDA.kext - (remove HDAEnabler! and legacy kexts) works at least on my board gigabyte X58 UD5 Bios 8E but should work on other Gigabyte boards too

put your DSDT.aml on program icon of iaslme ( http://www.mediafire.com/?jchmtymqlmd) - results in DSDT.dsl, which you can edit with textedit . Just drop after you edited the DSDT.dsl on icon of iaslme again and you have your patched DSDT.aml

Its easy
Now the exact patch

1. replace all entries AZAL with HDEF
(there are 2) use search

2. replace the entire Device (HDEF) entry with the following:

Device (HDEF)

Thanks for this DSDT Patch goes to Solar. Sound quality is good analog stereo although ahs several sound assertions at boot.

You have to use Line Out for analog Output (black plugin)



Edit: This DSDT patch works on 10.5.8 and 10.6 but not on 10.5.7.
