ALC888 sound won't work after using every method I've found

[SkuenD]

Hello.

I've installed Hackintosh on the following computer:

Motherboard: GA-P43T-ES3G rev 1.3 Bios F7

CPU: Intel E6500

GPU: Nvidia 430 GT ( Gainward DDR3 1024MB, although Mac reads it as 512)

Ram: 4Gb DDR 3 1333Mhz, although mac reads it as 1066Mhz

 

Anyways, I've been having some trouble finding a working DSDT For my motherboard since The 775 ones are harder to get... Tried patching myself, had some kernel panics, formatted, some more kernel panics after patching myself.

 

in the end I've found the DSDT auto-patcher ( http://www.insanelymac.com/forum/index.php?showtopic=235523 ) and it's all working great after using the ComboUpdate to 10.6.6, then [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] with:

UserDSDT with the DSDT Auto-patcher generated DSDT;

Lnx2Mac's RealtekRTL81xx Ethernet;

System Utilities;

( After a couple of days I've also installed Kext Helper b7 and Kext utility ).

I've also used an Nvidia update I've found in the web and it's recognizing my GPU ( Although wrong ram, i hope it's just a cosmetic issue ) And it all has been working great.

 

The only thing I couldn't get working is my sound.

By Gigabyte's Website, I have either ALC888 or ALC892, by Mac Info I have an ALC888.

I tried everything I found:

from MB I Installed ALC8xxHDA + AppleHDA Rollback.

after that didn't work I even tried adding the Non-DSDT HDAEnabler in case the DSDT wasn't patched currectly, still wasn't working.

I've tried ( of course after removing all the previous ) The VoodooHDA. It was a bit different - Under System Preferences->Sound i did have outputs, although all it produced is white noise.

 

I really don't know how to solve this issue and it's really bugging me and I'd be very happy if someone could help me solve this.

 

Thank you for the efforts,

Niv.

[SkuenD]

Thanks, sound is working :censored2: But i still encounter two problems:

1)There's an extensive white noise in the background, which is really bothering

2)I have a front-connector for headphones, and the os does recgonize it via System prefrences->Sound->Output, but when i switch to it, it's not working - no sound.

 

Any ideas how to solve these problems?

 

Thanks for all the help!

Edit:

I've seen here:

http://www.insanelymac.com/forum/index.php?showtopic=235523

that audio codec versions can change between revision ( for some reason I can't download that file ). Could that be the reason why the ALC8xxHDA + AppleHDA Rollback aren't working? if it can- how can i fix it?

I have the same problem. Also a lot of white noise. The best working solution for me is the VoodooHDA 2.7.2 from [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]. I have a Asus M4A89GTD PRO/USB3 mobo with ALC892 HDA and an AMD Phenom II x6 3.2 GHz on 10.6.6

I have a couple of motherboards with the 889a and have been using the 885/889a LegacyHDA successfully with 10.6.4/10.6.5 AppleHDA.

Does the new 8xxHDA require the 10.6.2 rollback? If yes, then it seems the previous LegacyHDA solution is still appropriate, correct?

 

tonymacx86: It will be identical support as your Legacy889aHDA.kext- you won't need AppleHDA Rollback with ALC8xxHDA on ALC889a.

So it's up to you whether you want to use the new one or the old Legacy889aHDA.

------------------------------------------

 

AppleHDA 10.6.2 Rollback: I think that after 10.6.3 (maybe 10.6.5) that support for ACL888 and lower was discontinued. So on the older [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] you had to select ALC888 and the rollback.

With the new [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] there is that combo ALC8xxxHDA, I think that it is smart enough to

detect an 888 and apply any rollback if needed.

 

Since it isn't working, I'd try removing any AppleHD*.kext (s) and all audio kexts and try it fresh, and only use the combo ACL8xxxx install. I've seen reports of unresolved microphone problems, so that is expected. If this experiment doesn't succeed, it's easy to reinstall voodoo.

 

I looked up your mobo and it says: Realtek Azalia audio chip...

http://www.kexts.com/view/595-voodoohda_ad..._to_alc892.html

and this was pretty recent and recommended http://macmanx86.blogspot.com/search/label/audio which I think you've read (and I didn't remember quite correctly):

 

"Introducing ALC8xxHDA.kext, a single combined LegacyHDA replacement for Realtek ALC888, ALC887/888b, ALC889, ALC885/889a, and ALC892 high-definition audio codecs. In order to initiate audio, this driver must be combined with a DSDT from the DSDT Database or HDAEnabler. For any codecs other than the native ALC885/889a, AppleHDA Rollback must also be used. All options now available in the latest [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url].

To update from an existing [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] LegacyHDA + AppleHDA rollback:

1. Delete LegacyHDA from /Extra/Extenisons
   
2. Open [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]
   
3. Select ALC8xxHDA + AppleHDA Rollback + System Utilities
   
4. Reboot "
   

Did you mention installing HDAEnabler? Those Revision differences and also Bios version discrepancy do matter with DSDTs. I see you've worked on this. To me, there seem to be a lot of complicated edits. http://macmanx86.blogspot.com/2010/11/mini...yte-socket.html

This is a tutorial which I will quote from. You obtained a pristine Ubuntu dsdt.aml. Then you break that down with iasl or something. You make the edits. then you convert it back to DSDT.aml and put it into /Extra. The tutorial covers 1156 and 1366, and they have some things in common. You need to find what those have in common with your 775. Here is a part which might affect you:

 

The next edit is for audio. Gigabyte uses a device name of AZAL, so we need to do a global replace with HDEF. Then we need to add codec information to Device (HDEF). All that is required is to inject layout-id and PinConfigurations.

 

Here is an example of what needs to be added for a board using an ALC889 codec and using our Legacy889HDA.kext:

 

Method (_DSM, 4, NotSerialized)

{

Store (Package (0x04)

{

"layout-id",

Buffer (0x04)

{

0x79, 0x03, 0x00, 0x00

},

"PinConfigurations",

Buffer (Zero)

{

}

}, Local0)

DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))

Return (Local0)

}

 

There is a problem with Audio break ups in 10.6.3 and later that can be corrected in the DSDT. The first is in Device (PIC) remove these two lines:

 

IRQNoFlags ()

{2}

 

The other fix for audio break ups is in Device (TMR) where Gigabyte has not yet added Hackintosh logic. We need to change:

 

Method (_CRS, 0, NotSerialized)

{

If (LGreaterEqual (OSFX, 0x03))

{

If (HPTF)

{

Return (ATT6)

}

Else

{

Return (ATT5)

}

}

Else

{

Return (ATT5)

}

}

 

To:

Method (_CRS, 0, NotSerialized)

{

Return (ATT6)

}

 

Mulcyber: So does your 775 have a similar section in the dsdt.aml and did you fix it? It's too bad that this example uses ACL889 rather than ACL888. Out of ideas.

 

"Gigabyte has not yet added Hackintosh logic to Device (HPET), so you will get kernel panics in AppleIntelCPUPowerManagement. The fix is easy; just change Method (_STA, 0, NotSerialized) to Return (0x0F) and to change Method (_CRS, 0, NotSerialized) to Return (ATT3)."

[SkuenD]

Is that relevant to me aswell? You say "889" alot in there ;-)

And there's no auto-patcher to do it cleanly? I'm kind of a newbie and screwed my dsdt once to get kernel panics, I'd like to avoid editing that as much as possible... at least for now.

EDIT

 

The specs for your mobo say ACL888/892 for the audio codec. I guess that was a clue...

[SkuenD]

I noticed this information under the the new [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] 3.3,

• Fixed HDAEnabler for ALC888 as it was 32-bit only, unlike the rest which were 32/64-bit.
  
• Renamed all HDAEnablers to include the codec it enables. So there is now HDAEnabler888, HDAEnabler888b, HDAEnabler889, HDAEnabler889a and HDAEnabler892.
  

 

I know, but I have a patched dsdt ( using auto-patcher ) so I should need to use it. and even if I do - i tried installing the ALC8xxHDA + AppleHDA Rollback with both HDAEnabler888 and HDAEnabler 888b ( after deleting the prevision enabler ). Both didn't work.

I have a different board but same trouble and same ALC892 (and same supposed ALC888). I am happy to say a user directed me to the solution above ( install ALC8xxHDA, AppleHDA Rollback, and the aforementioned non-DSDT HDAEnabler). The only thing different was that I first deleted my other attempted KEXTS (AppleHDA and HDAEnabler, and I think one more but can't remember the name). I also ran the cache and permission fix with it. It froze my computer, but I waited a good ten minutes before I rebooted, and now I have sound !! What do you think?

Mulcyber: So does your 775 have a similar section in the dsdt.aml and did you fix it? It's too bad that this example uses ACL889 rather than ACL888. Out of ideas.

 

That meant I realized I had used a dsdt.aml that showed how to fix the audio part which was not the same as your ALC888. It's because it had the best tutorial and I didn't have an example of a patched dsdt.aml that applied to ALC888 at that time.

Notice that there are some similarities, in general they both patch the HDEF section, but are not identical. I wrote earlier in this thread at 4:56 AM,

The tutorial covers 1156 and 1366, and they have some things in common. You need to find what those have in common with your 775. Here is a part which might affect you: "The next edit is for audio. Gigabyte uses a device name of AZAL, so we need to do a global replace with HDEF."

 

MaLd0n is very smart, but I don't know if his auto-patcher is smart enough for this and that it works for your 775 mobo. Have you read that in some documentation, that it will work for 775?

Another thing to consider is, MacMan wrote:

 

"Introducing ALC8xxHDA.kext, a single combined LegacyHDA replacement for Realtek ALC888, ALC887/888b, ALC889, ALC885/889a, and ALC892 high-definition audio codecs.

He said must. The DSDT Database is at tonymac and covers just 1156 and 1366 mobos. All of those DSDTs have had the same patches applied to them, including audio edits. I don't know, but I doubt that the patches MaLd0n's autopatcher makes cover the exact same ground as the DSDTs in the tonymac DSDT Database. I would be surprised if it did. So I suggested that you extract the content (dsl) of your current DSDT.aml and examine to see if the relevant audio patches had been made, or at least get an idea about it. Keywords AZAL and HDEF should help the search.

 

So ALC8xxHDA.kext works with the 10.6.2 AppleHDA Roolback AND a DSDT.aml from the DSDT Database applied with [url=&quot;http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/&quot;]#####[/url]. If the auto-patcher doesn't affect the same changes to the DSDT.aml that it generates, then this method isn't going to work, it doesn't meet the conditions. Since your audio isn't working, it casts suspicion on the auto-patched DSDT.aml to meet the requirements stipulated. I thought you should check that out rather than assume it. That is one idea, if the auto-patcheded DSDT.aml isn't right, try to fix it, or verify that it isn't complete.

 

My second idea was like the method that worked for Graham except I said delete all the audio kexts. Graham, "The only thing different was that I first deleted my other attempted KEXTS (AppleHDA and HDAEnabler, and I think one more but can't remember the name)."

Maybe that other kext is voodoohda.kext It does seem the 10.6.2 AppleHDA Rollback is needed.

 

Well, I did after all have one more idea. The DSDT.aml that the DSDT Auto-Patcher generated wasn't malfunctioning, but just wasn't complete. So I checked the documentation at the Auto-Patcher homepage in the unlikely event you missed something significant. I found the following, maybe you've already applied it, but it might be the missing link! I notice that you already provided a link to this page.

 

It seems that MaLd0n is very, very smart! He advertises this human-assisted audio patcher tool.

I actually did notice that part and thought it's probably related ( Gigabyte have sometimes more than 1 audio codec for motherboard types, like mine, it can come either with 888 or 892 so you have to check), But for some reason I don't have permission to download that file... I think it might be blocked for new users for some reason... anyway for a link from Megaupload/Rapidshare/etc?

I don't upload to those services. However, a new user sent me an email message from insanelymac, so there is probably a way for you to do that. Provide your email address in the email and I will send you HDEF_Gigabyte.zip it's only 512 kb as an attachment. I also sent you a message with my email address. http://www.insanelymac.com/forum/index.php?showtopic=235523

 

From the H.C.L instructions, * add EFI string for GT430 nvcap DVI/DVI choose correct RAM size

should fix the graphics ram reported problem you mentioned. I don't know if it's cosmetic.

[SkuenD]

So here's what I've done:

1)Removed the VoodooHDA.kext

2)Patched the DSDT using the patcher provided in email ( thanks :] )

3)Restarted to check DSDT loads up ok

4)Installed System Utilities, ALC8xxHDA + AppleHDA Rollback

 

And it's still not working... same problem as before ( no output recognized ).

What does your Mac info say? Does System Profiler say Audio (Built In) and list your Audio ID: 892 where mine says 889?

 

I've enclosed two screen shots... Do your Alert Sounds (System Preferences ->Sound) appear dark?

When they are grayed out I think it means that the driver is not installed. Are your boxes checked

like mine except mute which should not have a check. If your settings look good, then I dunno.

[LatinMcG]

the auto-patcher is making HDEF section different than tonymacs hdef .. once u get autopatcher dsdt. .edit hdef section to match tonymacs..

 

u have done so much to it that i think its best to start fresh. or refresh=reinstall 10.6.6 combo update and retry rollback hda?

[SkuenD]

Ok.

So, Gigabyte's website says about my motherboard that it either has 888 or 892.

So after running and trying and w/e, after getting the HDEF-patcher I've tried to patch it to 888, because my system said that's what I have. Apperently, It was wrong, after patching with 892 sound works with the ALC8xx + Rollback method.

I've tried ( of course after removing all the previous ) The VoodooHDA. It was a bit different - Under System Preferences->Sound i did have outputs, although all it produced is white noise.

 

I really don't know how to solve this issue and it's really bugging me and I'd be very happy if someone could help me solve this.

 

Your post was helpful because I had to replace my original GA P-35C with another socket 775 board to continue using my Q6600 CPU. I happened to choose a GA P-43T.

 

I had the same sound issues as you and others, and did not have success with ALC8xxHDA + AppleHDA Rollback.

 

I decided to try installing the latest VoodooHDA. For the first time, I had devices showing in Sound Preferences and obtained sound through Line Out. But I had the same white noise in the background as others described.

 

I was able to eliminate the white noise by turning the Input/Input volume level to zero for each input device. I did the same as well in VoodooHDA preferences, which is shown at the bottom of the System Preferences window under Other. (Hope this helps anyone else strugging with this problem.)

The above worked well on my board for 10.6.7 but VoodooHDA produced a KP when I installed 10.6.8 (Update Combo) on my test HDD. After trying a number of things, I went back to [url=&quot;http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/&quot;]#####[/url] 3.8:

This established sound and shows my built-in Audio ID as 892, which is correct for the 1.3 mobo version. I probably didn't need to install all of the other Non-DSDT kexts, but didn't realize it at the time.
