[GUIDE] ALC889a (with analog 5.1 surround)

[Gurruwiwi]

Holy sh...

Ok, off to work on that right now!

EDIT: LOL.. morm, I just booted into SL to start editing DSDT again, did nothing at all except pop in the SL HDD, no sound, but audio is fully mapped, and present in system preferences, active audio icon in taskbar !!

Tried playing around with agg.devices... no sound. Seems the built in audio's master volume is completely down and greyed out.

Going to try to edit that hex in, hope I do it right...

[mormegil]

If they are in sound pref then there should be sound! Have you tried plugging a headphone or mic to test? Internal speakers might be too soft to hear.

edit: My master volume in aggregate device is also greyed out for every port. Doesn't really matter.

[Gurruwiwi]

Quick question. Do I just copy the one you pasted into my dsdt then modify ConfigData to match it, or the other way around?

[mormegil]

@ Gurruwiwi

Doesn't matter. As long as it appears as above but with your configdata instead.

@ ajacocks

You seem to be doing fine with King's guide. I see all the required files in your attached package.
Once you're done patching the binary, you'll have to fix the plists. Your codec id in decimal should be changed to 283904131.
Your dsdt is fine. All it does is inject your audio. As long as you see an audio device in Sys Profiler it's all good.

Edit: I just saw the pic u uploaded. It's supposed to be that way if you haven't got the working plists.

Morm, please bear with me... this is all brand new territory for me.

I did ask you precisely that, and you replied the quote above!

Ok... so I copy exactly what you pasted into my dsdt
Question: Did I place it right like my example above?

Then do what with configdata? Right now it reads like this; its the "0" mod I made. from yesterday that woke up the right port mapping

Today is the day man, it has to be!

And I am learning like hell with you, I dont want you to do everything for me, I'm loving this experience! I'll surely pass this on to the little league, leaving you big boys to plow away into new territory!

Morm, while I was waiting I ran a small test. I think it can be useful for others to know, to not judge a KP on its own.

I cyclically rebooted in verbose, changing nothing. There is a sort of a pattern.

First reboot from "mapped - sound- but no audio heard" status


- KP
- 1x set of "Assertion "0"" errors during boot - no mapping
- 1x set of "Assertion "0"" errors during boot - no mapping
- 2x set of "Assertion "0"" errors during boot - mapping - audio shown - no sound
- 1x set of "Assertion "0"" errors during boot - no mapping
- 1x set of "Assertion "0"" errors during boot - no mapping
- KP
- 1x set of "Assertion "0"" errors during boot - no mapping
- 1x set of "Assertion "0"" errors during boot - no mapping
- KP
- 1x set of "Assertion "0"" errors during boot - no mapping
- 2x set of "Assertion "0"" errors during boot - mapping - audio shown - no sound
- KP
- 1x set of "Assertion "0"" errors during boot - no mapping
- 2x set of "Assertion "0"" errors during boot - mapping - audio shown - no sound
- 1x set of "Assertion "0"" errors during boot - no mapping
- 2x set of "Assertion "0"" errors during boot - mapping - audio shown - no sound
- 1x set of "Assertion "0"" errors during boot - no mapping
- 2x set of "Assertion "0"" errors during boot - mapping - audio shown - no sound

Seems something is being re-set... could it be a similar CMOS reset bug?

Going to try the DSDT and ConfigData, just waiting for your input as it looks like a hell of a lot of work...

EDIT: You posted while I was typing. Going to try it now.

Forgot to mention. When audio is mapped, I tried plugging in headphones and microfphone. Mic does nothing, but headphone makes system profiler hang. It does seem to try switching devices, but nothing happens. Beach ball spins round, OS stops responding, have to force quit profiler, but it struggles to do it. Once removed it manages to force quit, and OS response is back

OK, I made all the changes, mormegil, to AppleHDA.kext, including replacing 8508ec10 with 8308ec10. However, I still have no sound.

I noticed something interesting in my system.log, though:

9/6/09 11:11:55 AM com.apple.kextd[10] Can't load /System/Library/Extensions/AppleHDA.kext - no code for running kernel's architecture.
9/6/09 11:11:55 AM com.apple.kextd[10] Failed to load /System/Library/Extensions/AppleHDA.kext - (libkern/kext) requested architecture/executable not found.
9/6/09 11:11:55 AM com.apple.kextd[10] Load com.apple.driver.AppleHDA failed; removing personalities.

That's rather odd. I never changed any executables in the .kext file. Any idea what's going on, here? I'm running 32bit 10.6.

EDIT: I replaced AppleHDA.kext from my 10.6 install DVD, and that error went away. The failed sound assertions are back, of course, since this is a stock kext. I'm going to try putting the Info.plist files back, first, then hex editing the AppleHDA file, to see which broke it.

Thanks!

Thanks!

[mormegil]

That applehda.kext you posted earlier. Is that patched or not? and why do you have info.plist in root of AppleHDAHardwareConfigDriver.kext/AppleHDAPlatformDriver.kext? It shdn't be there. Should be under Contents.

[mormegil]

Replace the plists to the correct locations

[ajacocks]

Mormegil,

Thanks for taking so much time to help me.

I went back, and fixed the locations of the Info.plist files, and re-hexedited the AppleHDA file. I now get the AppleHDA.kext to load, but I get the following exceptions in my system.log:

9/6/09 11:42:27 AM kernel Sound assertion "0 == pathMap_aDriverInstance" failed in "/SourceCache/AppleHDA/AppleHDA-174.1.1/AppleHDA/AppleHDADriver.cpp" at line 1459 goto Exit
9/6/09 11:42:27 AM kernel Sound assertion "0 != createAudioEngines ( fPathMap_aDriverInstance )" failed in "/SourceCache/AppleHDA/AppleHDA-174.1.1/AppleHDA/AppleHDADriver.cpp" at line 172 goto Exit

I'll update this post, in a second, with the Info.plist files replaced with the ones that you sent me. What did you change?

Attached is the appleHDA.kext that caused those assertions to fail.

Thanks!
