Succesfully reainstalled SL on SL with method provided by Man of the Oak, thank you, now i can rest in peace and think thats all good with kext, compiled DSDT without errors and warning etc..

But i have a litle bug with sound, when some sound notification ocure, like send message in adium, or contact comes online, or just use system volume control, firstly i can hear crank sound like Crsdfjsn and after its going good. If were music on background all going fine and no cranky sound follows for notification.

Is there any fix for this? I thinking about workaround with some music player with song on repeat, and the trick is to get track with hight khz thats we cant hear or speakers cant play.
