Mavericks: No Audio - Realtek ALC AppleHDA [Guide]

[toleda]

I cannot load audio through MultiBeast because then I can't boot

Off topic. Until your boot problem is solved, audio will not work.

Let me clarify. There is only a boot problem when I use MultiBeast to enable sound. I have run MultiBeast for everything but the sound and I am able to boot just fine.

There is only a boot problem when I use MultiBeast to enable sound.

Not aware of a single instance where a MultiBeast/ALCxxx selection caused a boot problem.
Details? Screen shots? Console? IOReg? -v?

I'm sure it's an isolated incident. When I ran MultiBeast I selected the bare minimum for my system, and the restarted. I got hung up at the Apple Boot screen with the spinning icon. I reinstalled Mavericks and tried again, this time I did everything step by step, and it got hung up on the boot screen again after doing the Audio install.

I remember using the "-v" command and the screen said "something" didn't respond (or something to that effect) and it would try again, it did that several times and then would just do nothing. So I would reboot, reinstall Mavericks and start all over again.

I looked at Console and didn't see the error message from above. I really wish I could give you more....without having to recreate the problem!

Thank you for your patience, and sorry for my lack of knowledge!

I got hung up at the Apple Boot screen with the spinning icon.

An audio problem boots with the result of no audio. The Apple spinning icon is a graphics problem. Post in the Installation or Graphics Forum.

IOReg says audio is working. See No Sound, Post #1.

Thank you toleda for the answer, let's try to understand why there is no sound:

let's try to understand why there is no sound:

Everything attached says sound is working. Test Post #1/No Sound/Audio Outputs/Headphones with iTunes. Reply with screen shot of SystemPreferences/Sound/Output and a new IOReg.

What did you do with realtekALC.kext?
Attach View attachment debug.logView attachment Clover iMac.ioregView attachment SSDT.amlView attachment Archive audio.zip and debug.log as noted in Post #1.

After you messaged, it started working. I rebooted and it stopped working

RealtekALC.kext is in the kext folder, EFI/CLOVER/KEXTS/10.9/ I also have FAKE SMC.kext installed here.
