Folks,

I tried to set up ALC898 audio configuration with config.plist in Clover's EFI filesystem. It still displayed "No output devices found" and "No input devices found" in Preferences/Sound. I followed Toleda's Clover ALC instructions. Look at my attached files.

Thanks,
Sword7

"No output devices found" and "No input devices found" in Preferences/Sound.

Attach S/L/E/AppleHDA.kext.

Hi, I keep thinking I have solved this problem but somehow it keeps coming back. My MB is Z87X-UD5H. I installed ALC898 and HDAEnabler - First with Multibeast 6.01 when I installed Mavericks 10.9.1 and then with Multibeast 6.2.1 when I upgraded to 10.9.2. I have tried various downgrades to older versions when my audio starts to go bad and it works for a few days and then comes back - very strange.

Basically audio drops out for a second or so every few seconds.

I have attached the IOREG file here: View attachment MAC1.zip

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

Thanks

Ok, here are AppleHDA.kext and config.plist.

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.
