here is the IOReg file.

I just installed Mavericks 10.9 to my Acer 5935G laptop and after that I installed Multi Beast 6.0.0 version. I choose EasyBeast and GraphicsEnabler=Yes and Realtek ALC 889 without DSDT (you can see in picture at attachment).

after that I can see sound icon on top black (enabled) and I can see in sound page all sound drives. the problem is I cannot hear sound. (you can check those picture in my previous post about sound settings).



many thanks for your helping.

the problem is I cannot hear sound.

If you tried all the audio output devices and there is not sound, Acer has configured the audio codec and audio devices incompatible with OS X AppleHDA.kext audio. Search the Laptop Forum for a solution.

Let me explain;

I reinstalled mavericks to my laptop now. It's totally clean and new. and then I just installed multi beast (please check picture what I installed.)

in sound section there is no audio (if I install Realtek alc 889 without DSDT by multi beast).

Works as designed. If there is no audio enabler (kext, dsdt, ssdt or bootloader) there is no audio.
