I got it installed but no audio. I installed voodooHDA.kext to extra/extension folder, sound came on but very garbled. Installed same kext using kext helper, same result. I cannot get the DSDT to compile without failing. Would it be better to add the voodooHDA.kext before booting to SL? Any other suggestions to get the sound going without involving DSDT?

Sound is fine using a USB headset.
