So I have an Alienware M17X (second revision-the newer one) and I've been trying for weeks to get audio on this thing to no avail. I've tried the voodooHDA kext and I do get audio, but its so choppy and buggy to the point that it's unusable.
I believe I have IDT High Definition Audio. In System Profiler, it says my device ID is "0x10DECB79"
If anyone has any Idea on how I can fix this, please help.
