Out of curiosity, do you any difference in system logs when patching 11d4198b vs. 11d41984 (sound assertions and ambient noise reduction)?

Nope, it is exactly the same in my experience with the same 2 sound assertions (AppleHDAPath at line 1360 & AppleHDAEngine at line 519).

A bit improved AppleHDA 10.8.4.
It remembers volume settings and the volume bar adjustments work as expected.

Thx to TheEnthusiast for sharing.

Hi!
So, I've decided to give MaciASL (v1.2) a shot and go with "easy" DSDT making.
Took F.42 (that's current) BIOS ACPI dump from Linux, decoded, then proceeded exactly as in kpkp's first post in this thread through applying Rehabman's repo patches.
No errors, 7 warnings, got DSDT which is about half the size of the original - hmm, maybe that's ok.
Booted, all looks good except that sleep doesn't work at all. PC wakes up immediately.
I remember seeing other people with the same problem, but I can't find these posts anymore.
Anyone has come across this? Any ideas?

I just did my DSDT again using the version 1.2 and it still works fine (sleep)... but i did not update my BIOS, maybe that is to blame?

hard to say. sleep works fine with "old" DSDT.
how big are your DSDT files (text and binary) after patching?

I'll have to do manual patching sometime later and see how that works with F.42.
Or maybe mighty Rehabman will come to help with some suggestion...

upd.:
but I see that CPU temperature is much higher now, it may go up to 100 ℃
probably BIOS impact, I see that happening with all DSDT versions I have.

That is normal that the size went down, Rehabman did some streamlining (it went from 130+kb to 55kb, going from memory). For example my desktop has only a 8kb dsdt after Master Chief done some crazy stuff (for the time) with the dsdt, there is a huge amount of code in the DSDT that has no effect on the OSX.

It think it might make sense to diff your two DSDTs.

General method:

# disassemble both
iasl -d dsdt1.aml
iasl -d dsdt2.aml
# compile both
iasl dsdt1.dsl
iasl dsdt2.dsl
# disassemble both
iasl -d dsdt1.aml
iasl -d dsdt2.aml
diff dsdt1.dsl dsdt2.dsl

But check your system.log for wake reason. And check your BIOS settings for wake on usb/wake on lan.

I compared the "original", unedited DSDT tables from F.40 and F.42 and there is only a single change (pic attached).
Probably HP made changes in other tables.
I guess I can continue to use F.40 DSDT with F.42 BIOS.



And yes, wake is caused by "Wake reason: EHC2 EHC1", could it be a problem with USB ID's?

Something removed from an _INI method. Bug fix of some sort?

What USB patches do you use? What does ioreg show for native IDs?
