[GUIDE] ALC889a (with analog 5.1 surround) - Page 15

Morm,

I greatly appreciate your help, I do.

But, though dsdt n00b, I'm certainly not OSX illiterate, on the contrary. Been at this since early Tiger. I know what a KP is and how to handle them, and I am telling you that, possibly exactly because of this weird alc889a behaviour, there is a reset going on that has nothing to do with your dsdt applHDA etc... but it doesnt like dsdt being changed, and when I f*cking need to restore its because I cannot bring the system back up. safe boot too.

What would you do, if suddenly, right after nvdresman blacks out and brings up your desktop, it instead flashed black and blue in 5-10 second interval, having just a little white cursor at the top left, where you can actually type from your keyboard strange characters (that dont match what you type) right into a pitch black screen?

And the reboot cycles, which are far from typical ? either a kext works, or it doesnt, or it KP's... never heard of a kext that did all three !

Even removing all video kexts, removing com.boot.apple.plist strings, removing dsdt, nothing works to bring my system back up.

I have explained this phenomena before, and that is the only reason I have to restore from a CCC image. It takes 7 minutes, fix UUID, and back to action.

And this system is rock solid, except when tampering with audio. I've thrown at it highly intensive tasks (protools fully loaded with plugins with reason rewiring) and it behaves like a charm. HD video, while having Ubuntu and Windows 7 both running, each on their own screen (spaces). I've tested a for 4-5 days periods non-stop and it is rock solid. Oh, and playing Trackmania virtualized in Win 7.

this to my own disbelief, how smooth and stable. 64bit SL is unbelievable!

I have no issues whatsoever to fix, except audio.

The video f*cks up, and nothing brings it back, if there is please tell me.

There is something definitely going on, and I suspect a sort of CMOS rest bug, similar at least.. look at my reboot cycles. My gfx must crash, possibly because of hdmi audio trying to be used or something on one of those resets...?

Plus, I am still using an AppleHDA which you kindly patched, based on generic alc889a info, now that I finally manage to get my very own codec dumps, why cant we make an appleHDA for my system?

We are so close, why would you jump ship now? I mean, this is the place for exactly this, if you dont feel like sharing anymore, that is absolutely fair, this is a time consuming affair, prone to not working until it does. Just say the word, but please dont imply that I am idiot enough to restore at a sign of a simple KP.

I went back to vanilla AppleHDA and "erratic" reboot issues happen no more. No ports are being mapped, audio device 12, no KP's, asserrtion"0" errors, and in 15 reboots between 32 and 64... no issues whatsoever.

I would again, guess, a good appleHDA patch for my system might fix this thing.

Use this plist and follow this guide

terrorgen · #**145** 09-08-2009, 03:58 AM

referring to the guide, the LayoutID i got from AppleHDAHardwareConfigDriver.kext was 12, but in the plist it was 888. Should I just change it?

mormegil · #**146** 09-08-2009, 04:04 AM

Yes. You should be using layout 12 in your dsdt.

terrorgen · #**147** 09-08-2009, 04:06 AM

I finished editing applehda.kext, put into /E/E of my boot thumb drive, reboot with -x32.

Doesn't work...

mormegil · #**148** 09-08-2009, 04:12 AM

have you injected hdef into dsdt?

terrorgen · #**149** 09-08-2009, 04:19 AM

yes i did...
anyways, I got sound working by installing it into /S/L/E of the SL drive (I use a flash drive to boot SL)
now it's time to make 5.1 working

THANKS for all your hard work!

ok I think it's best to remove the guide since it doesn't seem to work for anyone. It's that or the one who do get helped don't post back.

What you think Morm? It's like since I've posted the guide you got another full time job solving this stuff
