no sound after upgrade Lion to Mountaine Lion ALC889

[jlopez37]

I have upgraded my system Lion to Mountaine Lion. After that the sound doesn't work. It have an ACL889 sound card. With Multibeast for mountaine Lion I installed driver for this sound card. AppleHDA.kext doesn't load. kextutil displays this message:


sudo kextutil /System/Library/Extensions/AppleHDA.kext

Any idea?

Solution:
1. Download de latest version Multibeast 5.5.5
2. Reinstall USERDSDT and ALC889. It's very important install USERDSDT too. It's mandatory.
