no more sound after 10.9.4 update

[SOLVED] no more sound after 10.9.4 update

Hello,

Since my system was pretty stable I recently kind of lost track of all the updates in the hackintosh community. I bet my problem is thus quite easy to solve. Sorry if my question seems stupid.

I was running 10.9.3 on a system composed of:
- Gigabyte ga-z87x-oc (is that an Intel 8-series MB? or a 7-series?)
- Intel i7-4770k

After upgrading to 10.9.4 I downloaded Multibeast 6.3.1 (I was previously using 6.2.1) and wanted to reinstall sound (ALC892) and TRIM drivers as usual after a system update. I got the following error message in Multibeast (attachment )

Then I checked this post:
http://www.tonymacx86.com/428-multibeast-6-3-update.html
mentioning the following:

"MultiBeast 6.3 Audio Changes:
As part of the removal of "With DSDT and DSDT-Free" from Audio -> Realtek ALCxxx, we are no longer using HDAEnabler.kext. Each patched AppleHDA provided in MultiBeast is now dependent on the Chameleon/Chimera module HDAEnabler.dylib or a DSDT or SSDT with a layout-id of 1, 2 or 3. During installation it will delete any HDAEnabler if found. In addition it will add HDAEnabler=Yes and default HDEFLayoutID=01000000 to /Extra/org.chameleon.Boot.plist unless "Optional EFI Installed Bootloader Support" is selected.

All current users of MultiBeast 6.2.2 should seamlessly transition to Chimera 3.0 and HDAEnabler module by updating bootloader and Realtek ALC kext to the latest versions."

Click to expand...

Thus I ran Multibeast 6.3.1 again and installed the usual sound driver (ALC892) together with chimera v3.0.1 as a bootloader.

I still don't have sound after reboot... Everything else seems to work fine.
Probably I missed something obvious. Can Someone help me out?

Thank you very much in advance for your help.
Best,

Multibeast 6.4 solved the issue (sound is back)
