Kernel Panic with voodooHDA - ASUS K451LB Laptop

I installed Yosemite on my asus  k451lb laptop. It has 4200u i5 processor (haswell), intel 4400 and nVidia 740m graphics, ALC233 audio.

I installed with /haswell -no-zp bootflags. otherwise a kernel panic would happen where the microphone somehow  starts to relay sound to the speakers

Now after installation,whenever I install voodooHDA I get same kind of kernel panic.  If I use safe mode then I can login, but there's no sound. Only if I remove the voodooHDA kext I can boot normally (no sound).

I tried AppleHDA kexts,they dont work.

If I add usb sound devices after booting, they work. But if i add them before booting, I get kernel panic .

If anyone is interested in helping me, I can provide more information.

Regards.
