Hi there... i got a fully working hackintosh running 10.7... After a while (at least some hours) something goes wrong: the sound will from here on only work for appflications that are already open. e.g: i have spotify and Logic running, so the sound is working here, but when i open youtube then and try to play a video then there is no sound... just as if i open vlc player, trying to play an mp3 file: no sound. after a reboot it's all working properly again... dmesg gives me the following error: IOSurface: buffer allocation size is zero
