They both don´t work! A general question: I think about buying another board which also has the ALC887 chipset, is the problem I am having a general problem with ALC887 or do they in general work? I looking for the GA-Q77M-D2H which should not need a DSDT because of the Q77 chipset, but what is with the audio codec? Thanks!

Here is my codec dump: http://www.sendspace.com/file/p53dzg

Hey! Sorry for the long time since my last post! I did a clean install and tried both versions of dsdt + applehda! Even with -v -f and deleted kernel cache the applehda doesn't autoload! When I loaded it manually with kextload the kext loads successfully but nothing changes!

It seems the applehda isn´t loaded at all! I´ll set up a clean install this weekend and try it again with the patched dsdt + applehda! Maybe something went wrong with all my tries! I´ll tell you if it works!

Both didnt work for me! I have no idea whats wrong with my mainboard

I successfully downgraded to 1503! Here is my new untouched dsdt for 1503: http://www.sendspace.com/file/jgefxf I hope this one is not corrupted, too!

I use the latest available Bios: M5A97 BIOS 1605!

Didn´t work! Here is my original untouched DSDT: http://www.sendspace.com/file/yvxpew Thanks!

Maybe I found the problem: Systeminfo lists my audiodevice as Azalia Audio with different ids than my linux dump says. Can I inject these ids into my dsdt so osx begins to see it as ALC887? The address is: 1002:4383 I took a screenshot of my systeminfo and ioreg section of HDEF, where exactly the id from above is shown but no driver is loaded I think?! Archiv.zip

Hey thanks for your help, but the patched dsdt +applehda do not work! No device shown! I added a screenshot of my ioregistry! pic1.tiff

Hey guys! I am trying to optimize my DSDT for my system (ASUS M5A97) and ran in trouble with my audio codec! I already successfully patched my Ethernet to builtin and my Graphicscard to PEGP, both working! The plan is to use a patched AppleHDA instead of voodoohda! I tried a few different already patched applehda.kexts and think the problem is my DSDT! With Ioregistry I located my soundcarddevice as SBAZ. I tried replacing every entry for SBAZ with HDEF. The system still boots but doesnt recognize the card at all! Thats my original entry: My modified one: The DSDT compiles but Audio isnt detected! I also patched my AppleHDA manually with this guide http://www.insanelymac.com/forum/topic/140941-alc889a-gigabyte-intel-now-having-a-working-front-mic/ I added my DSDTs plus codec dump, its the newer version of the ALC887! If anyone can help my fix this problem that would be great! Thank you! dsdt.zip

I tried it and also edited my NVCAP but no luck. Still getting Black and white..

Yes I tried GraphicsEnabler=Yes with the same result! Edit: Ohh no I made a mistake. The Vram size is wrong. I disassambled my graphics card and found out it only has 512mb so the compiled dsdt must be wrong. I got the NVram string 0400000000000300040000000000000700000000. Is it possible to use my card with this patch just by editing the vram size?

Hey thanks for reply! The DSDT itself compiled successful but now I´ve got black and white rectangles. Before I patched the DSDT the system always loaded something like NV50HAL. Do I have to remove this kext?

Hello! I tried the guide on this site with the following patch i have found, which is exactly for my graphics card, but i get 201 erros! I tried to inject the hexstring in chameleon before, but it gave me just a black screen! The problem i have is that i dont have a P0P device and IORegistryExplorer tells me its PC02@2. I´ll attach a clean windows extracted dsdt.aml ! Thanks alot!!
