[GUIDE] ALC889a (with analog 5.1 surround) - Page 4

Snow · #1 08-28-2009, 10:57 AM

Small observation, the sound indeed is far too low and I have to turn the volume way up, so much I start to hear noise (normal with analog setup I guess)

Any ideas?

Update: and that my friend seems to be fixed by setting db to 0 for the line-outs in audio/midi config panel. Maybe I should seek a solution first and then post if its unsolved. I'm a bit excited I got 5.1 working guess.

Ah yes. I got that too. Somehow the channels are not mapped properly by default.

Yes, dsdt.aml you can just reuse for Leo but AppleHDA you can't since 10.5.8 uses an older version. AppleHDA.kext:Contents:PlugIns:AppleHDAHardwareCon figDriver.kext:Contents:Info.plist
Copy and paste ConfigData with LayoutID 12

AppleHDA.kext:Contents:PlugIns:AppleHDAPlatformDri ver.kext:Contents:Info.plist
Copy and paste the blocks with LayoutID 12 under Layout and PathMapID 9 under PathMaps

Alright bro, I'll try that after lunch.

Also, 5.1 in quicktime seems to be fixed with Perian audio options set to Multi-channel output.
Positional sound is quiet good too I might add.

And another question, would adding my 8800GT to the dsdt make any difference compared to EFI string in boot.plist? if yes how would I do this?

Later bud

Update: Is it ok I share the Leo AppleHDA with you so you can modify because there's a lot of code innit and I don't want to mess things up. I think I've done some of the work, can't remember.

Thx!

Hi guys,

I've followed your thread and am in dire need of your help!

I too have alc889a

I am audio and SD card away from a perfect install of SL 432, using Cham2rc1.

Let me just give you some info I think is relevant.

Last week I bough a new HDD for my laptop, installed SL fresh over 8-10 times, successfullly becoming more KP. On Sunday I realized the drive was bad. It wouln't even format right. But during the weekend I managed to get alot of things done, like testing video string working, AHCI etc etc.. on my first few tries I managed to get audio working perfect, spdif etc, no internal mic, but external mic working fine! I would be more than happy with that!.
Plus, the woofer was present as music had lot more low end. I did not go into Audio Midi as I only now found this out (I thought it was only for midi connections!).Sound was cristal clear, loud and healthy, zero click or pops.

Then the system broke and I had to restart yet again, but the drive didnt last long. Since I was having so many problems, when something worked, I copied a backup for the future. I didnt have time though, "warmd" KP crashed. And you know how the download folder can get really confusing really fast, because I knew I had very little time before a permanent KP, and so basically I cannot remember for sure which kext I used, but I have a very warm feeling it was AppleAzalia kext from electro's Live website hosting loads of drivers. On Sunday I realized the drive was bad. It wouln't even format right anymore.

http://cid-8b65993ef55cf014.skydrive...=?view=details

It's the first one, title ALC883 (Azalia). Either that or one of the latest VoodooHDA woke up the card, it was late and I was dead tired.

So, brand new drive, fresh SL with gfx, ethernet, webcam, bluetooth, ICH9m working, smbios.plist edited to match a macbook pro 5,1... and is rock rolid !

This is with or without dsdt.aml in neither root nor Extras.

I spent 5 hours yesterday just doing this...

Install (X) kext in E/E - repair perms, reboot with -v, keep my eyes peeled for info,
Install (X) kext in S/L/E - repair perms, reboot with -v, keep my eyes peeled for info,

Where (X) - is any and every audio kext compiled to 64bit SL I could find !

Nothing - in System profiler I get (from vanilla AppleHDA.kext)

Code:

Device ID:	0x10250146
  Audio ID:	0

Note that this Device ID differes from all others!

Now, up to now I wasnt using my 10.5.7 dsdt.aml file in root or Extras... so I decided to copy them to both locations. Basically repeated the install, repair, reboot procedure for all kexts.

All other kexts read:

Code:

DEVICE ID: 0x1458A002

with no Audio ID, just that line

Then I kind of lost heart and decided to move onto ethernet, woke that up and shows fine, then I try another voodooHDA and I get sound! After 20 million kexts. Out of the blue! No mic in, not external mic (but this time "Mic" is present is preferences) I installed it to S/L/E and I think vanilla AppleHDA was there too. In system profile is read just like the above, but sound works!

So I go, YEY!, I'll try moving that one to Extras/Exten so I have a vanilla system, and back it up straight away!

Reboot, no audio. Move the same kext back into S/L/E... no audio !! wtf !?

Most kexts dont give sign of working during verbose boot. Some, that I tried in E/E come back complaining about dependancies, but when in S/L/E show no lifesigns during verbose boot.

what is going on? a kext works one minutes, not the next? Yes, repaired permissions etc.

Should I remove AppleHDA vanilla as principle? (tried)

Should I use dsdt.aml or not? (I havent tried patching as it seems damn complicated!!)

Also, and this gets to me more than anything... if I boot up SL USB Installer, and go in system Profiler, this is what I get

Code:

 Device ID:  0x1458A022
             Audio ID:   12

            Available Devices:
            Internal Microphone:
                 Connection: Internal
            Speaker:
                 Connection Internal
            External Microphone:
                 Connection: 1/8-inch Jack

This is my lspci info;

(ICH9 Family) HD Audio Controller [8086:293e] (rev 03) 00:1c.0 PCI bridge [0604]: Intel Corporation 82801I

I guess I could go the dsdt patching route.. but I've gotten audio before and I dont get it why SL is being so picky. Never tried dsdt patching and it intimidates just by looking at it.
When booting with vanilla AppleHDA, I get the following verbose messages;

And if you look, it says "sound assertion "0" - is that related to Audio ID: ?

Why should I need dsdt patching if I've gotten sound before

Thank you for the long read, I wanted to give as much info as possible

Just went through King's tutorial...

First step, problem, graphviz does not install in SL

mormegil · #9 09-02-2009, 12:34 AM

Simple.

Either use the 2 plist's I made for Snow and insert them into your SL AppleHDA (rename them first)

or

go here. tmonkol's unified plist or so called LegacyHDA.kext should be the easier way out. Look for the latest package dated 6-8-2009. Don't really have to go through King's tutorial since your audio chipset has already been excellently documented.

Next step is DSDT. Don't really think it's that complicated. Again, tmongkol has a link to DSDT Patcher by fassl. Just a matter of running it once to generate your dsdt.aml.

Decompile it:

Quote:

iasl -d dsdt.aml

Insert HDEF code into dsdt.dsl
Recompile it:

Quote:

iasl -ta dsdt.dsl

I finally got sound to work on my EP45-DQ6 motherboard but I am noticing that more sound is coming out of one of the speakers than the other. I only have 2.1 speakers. Anyone noticed something similar?
