Audio then no audio

Hi tony, awsome job you are doing on this project.
Been trying to solve a dilema I have
Using your guide iboot-multibeast-install-mac-os-x-on-any-intel-based-PC

Using iBoot Nvidea, I boot with iboot, change DVD to SL Retail 10.6.3, Complete the install
no problems,

I do have sound after the OS install.
I then install MultiBeast, do my reboot, reset bios to boot frm HDD
NO sound.

If I reboot again Using iBoot, I DO have sound.

My question is then, what can I take from the iBoot CD do give me sound, or does Multibeast have a setting extra I need for the sound card.

I also ran the same setup Using iBootSupported, MuliBeast same settings, No sound after
booting to HDD.
Boot again using CD, I DO have sound.

Just pulling my hair out.
Thanks

Problem Solved

so simple I over looked it.
I installed Kext Utility.
Found a VoodooHDA Kext, dragged it onto the util Icon, enter password.
Installed successfull.
Reboot,
Check sound,

Yipeeeeee

Thanks again Tony for a great site.
