Not the OP, but I built one based on one of these guides 2 years ago. The only problem I have is that once in a while (1-2 a month) the sound doesn't work after resuming from sleep. I have to reboot to get it back.
Otherwise I don't have any issues. I'm running the latest Mavericks, could install updates etc.

I have a 2013(?) Mac Mini that was running Lion (and then Mavericks) and it did the same thing with HDMI audio on every single unsuspend. It took months for an update to come out that finally fixed it. Not saying your problem isn't due to hackintoshing, but getting the real thing (since 2005 and the first mac mini, for me) hasn't been problem-free either.
I built a Yosemite based Hackintosh a few weeks ago and had a same problem except it occurred almost every time computer wakes up. Solution was to unload audio drivers before computer goes to sleep and then load them again when it wakes up. Somehow it works even when kext is in use and cannot be unloaded.
Otherwise I don't have any issues. I'm running the latest Mavericks, could install updates etc.
