did you find out, how to fix this problem?
I've got a similar Problem with my Hackintosh.
I installed from Niresh CD Mountain Lion 10.8.5 , and it's allmost working fine, except the audio. I allready tried out different Versions of Voodoo HDA, but nothing helps.
Every time, I'm watching a film, after one or two secconds the sound starts to stutter, it's really horrible.
but the strange thing is, when I'm moving the USB-mouse round and round, the sound is ok - funny, isn't it.
Does anyone have an idea, how to solve this Problem?
