I've got everything running correctly in SL except my audio (Intel IDT 111d76b2). I've tried different methods, but can never seem to get everything to function. I either have an issue with no sound after sleep if I use AppleHDA or I have issues with not being able to control the volume with VoodooHDA 0.2.2 64bit.

With AppleHDA I patched the kext and inserted 'Device (HDEF)' into my DSDT and can get audio. However, after sleep I no longer have audio. I've tried some work arounds, but no dice. My last attempt I borrowed from here, but still no sound.

With VoodooHDA 0.2.2 64bit, I can get it to load after sleep, but I can't control the volume and the PrefPane "can't map memory". It stays at one level and I can't even get it to mute. With VoodooHDA 0.2.1 32bit I can get the volume to adjust after choosing PCM #0 in the sound preferences (although it is a little low), but I haven't come across that version capable of 64bit. I wouldn't care, but 64bit seems to process things much faster and I don't have SATA speed issues. Any suggestions?
