I had problems with sound after installing Lion 10.7.5 Combo Upgrade, I have Voodoo HD, but the problem was I lost all sound, i tried reinstalling a hacked AppleHDA kext, but it didn't work. Voodoo only recognizes the HDMI audio, not the ALC 889 Intel based audio.

I have an Intel i7 950 3.07 Ghz, 6Gb RAM, 2 2Tb HDs, XFX ATI HD6870 1Gb DDR5, Intel Extreme DX58SO.
