Mavericks: No Audio - Realtek ALC AppleHDA [Guide]

[toleda]

I would really appreciate some help to solve this once and for all.

Unfortunately, Off Topic.
You have audio, not perfect. When there is a fix, a new thread will be posted.

followed Toleda's Clover ALC instructions.

Operator error, wrong patch. The correct patch is audio_cloverALC898-90_patch.command, not audio_alc898-92_patch.

Fixes, choose one:
1. With installed S/L/E/AppleHDA.kext, undue all cloverALC patches, rebuild cache and restart.
2. Delete S/L/E/AppleHDA.kext, install native AppleHDA.kext*, run audio_cloverALC898-90_patch.command, restart.

* native AppleHDA.kext: rename Desktop/audio_ALC898/AppleHDA-orig.kext to AppleHDA.kext

Yeah! I got it. Good news! I finally got audio working now! Look at my screenshot.

Thanks again!

I can't figure out where I went wrong. Help? I tried to set up ALC892. I still get the 'No output/input devices found' error. I followed Toleda's Clover ALC install instructions. Here's my config and kext....

I'm using....

OS X 10.9.2 with Clover install. Everything else works.

What did you do with realtekALC.kext?
Attach IOReg and debug.log as noted in Post #1.

My Audio isn't working, I installed Realtek ALC with DSDT/ALC898 (Multibeast)

Intel Core i7
Gigabyte GA-Z87X-UD7-TH
NVIDIA GeForce GTX 760

My audio ID says 0
AppleHDA.kext says Version: 2.6.0-toledaALC898

inside DPCIManager i have 2 Audio Devices both with blank Codec IDs:
0x80868C20
0x10DE0E0A

Chameleon Bootlist:

Would i need to edit the permissions for the .kext or edit it ?

No. Run MultiBeast/Without DSDT/ALC898

I'm having trouble following this guide. I've got an MSI mobo with ALC889 audio. I cannot load audio through MultiBeast because then I can't boot and have to reinstall Mavericks or restore to prior to the MultiBeast install.

Audio is the missing component of my install. Help me fix this problem please!
