Same problem, 2x Intel High Definition Audio.

D'oh... I really don't know what's going on here. I did a complete fresh install on a HDD that had never been used. I can try and reinstall OS X again and see what happens.

Is there anything else you'd suggest?

Clean install, no audio. Reply with a screenshot of System Information/Audio and IOReg,

Toleda,

Thank you for all your efforts with this endeavor. Hopefully I have all the correct info you require.

Mobo: GA-H67MA-UD2H-B3 (Bios rev F8)
CPU: I3-2100
Video: Sapphire Radeon HD6850 2GB
Audio: ALC889

Fresh Install 10.9.1 > MultiBeast w/ user DSDT >
Audio Installed via Multibeast: without DSDT ALC889

NO Audio, able to adjust audio levels and elect input/outputs. Line is Plugged into the Green Line In input.
Not using npci=0x3000, or any npci.

Please let me know what else you need if at all. Thank you so much.

####- UPDATE - ####
After more troubleshooting Audio is coming out of "ORANGE" Center/Subwoofer Line. I guess the mappings are wrong? Reading IOREG is very knew to me So I am not sure what I am looking for. But if I need to run it out of this port from now on... so be it. Thanks again Toleda.

There is no Green Line In; there is Green Line Out and Blue Line In.
IOReg says audio is working.

Ok here goes nothing. Keep in mind please that I am new to this, as I have had actual mac devices in the past, so never really got into this.



OS: 10.9.1

Motherboard: GA-P55A-UD3

BIOS: V2.0 F11

Processor: Quad Core i7 2.93 GHz



What Codec? ALC885, 887, 888, 889, 892, 898 or 1150

All of my research says ALC888 Legacy



Which Audio ID? 1, 2 or 3?

I have 6 3.5mm outputs on the back, so I tried 1



What Injection? kext, dsdt, ssdt or Clover?

I used the DSDT method on http://www.insanelymac.com/forum/files/file/130-realtek-alc888-applehda-audio/



I checked the output settings under System Preferences>Sound and the only thing I could see is my Apple TV. I have a Mic Working, but that is only due to it being USB.



I also went into my console, and could not find what you were asking.

I know Mr. Toleda is busy helping, so if someone wants to help me if I am missing something so I am not wasting time I would like that.

Clean install, no audio. Reply with a screenshot of System Information/Audio and IOReg,

I completely reinstalled 10.9 to a freshly formatted drive. I then used Multibeast 6.0.1 to do a User DSDT Free Instillation with the only additional driver of the Audio>DSDT Free>ALC898 driver. In Sys Info/Profiler>Hardware>Audio I'm showing only one Intel HD Audio Device which is a good sign? But still no audio.

Here's the answer to the questions and attached files.

1. Mavericks 10.9, GA-Z77-UP5-TH, BIOS F11, i5-3570K, MSI NVidia GeForce 660Ti
2. Multibeat 6.0.1 Without DSDT> ALC898, Audio ID 1, kext injecttion via MB, mavericks-no-audio-realtek-alc-applehda-guide, AppleHDA.kext 2.5.2-toledaALC898
3. No DSDT

Hello, Toleda.

First off, thanks for sharing your knowledge with us. I have a question regarding my problem with not getting sound on my system using the ALC892 kext. I have an Asus P8P67 Pro board with 3xxx BIOS, and I know it's not supported. However, you mention two alternatives: 2xxx BIOS downgrade, 7/8 Series upgrade. I'm not too comfortable downgrading my bios because I'm afraid I might screw something up. What do you mean by '7/8 Series upgrade'?

My original question is, do you think bios 3xxx will eventually be supported? If I don't want to downgrade, is there hope for a fix to the issue on these boards/bios'? If you think there will be no fix/workaround, is there a guide for downgrading that you recommend? Again, I don't feel comfortable downgrading, but if it's my only option now and for the future, then I'll have to do it.

Thanks in advance.

P.S.- Before I realized my board was not supported, I tired to run your audio_alc892-91_patch.command patch, but I could not run it because it kept saying I don't have sufficient privileges to run that command. Any ideas why? I had read/write access under Get Info.


Here are my system specs:

OS X 10.9.1 / ASUS P8P67 PRO / BIOS 3602 / 3.4 GHz Intel Core i7 2700K (Sandy Bridge) / Gigabyte Geforce GTX 760

Procedure: First I tried Multibeast 6.0 for Mavericks, then I tried Toleda's guide / AppleHDA.kext_v2.5.3

No dsdt.aml


I'm sorry for not being able to post my IOReg or screenshots as I'm at work right now and of course I don't have access to my computer at this moment.
