Just updated to 10.7.2 and lost audio, figured no problem, ran [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] and used rollback, it failed. I dropped in my kext for AppleHDA from 10.7.1 and ran system utilities, it rebooted and it still failed. I am stuck at 10.7.2 without audio 889, board GA-H55M-UD2H rev 1.3
