Crackling Sound, Only in Safari

[powermapler]

Hello,

 

So I've got a bit of a strange issue with Yosemite that is starting to drive me insane. I'm using the latest VoodooHDA drivers for audio, and generally they work wonderfully. However, when I'm watching a video in Safari (generally YouTube or Vimeo), the audio will crackle for awhile before slowly going to normal a minute or two into the video. Outside of Safari I have no issues whatsoever, and even within Safari they go away on their own, but when I click on another video they come right back.

 

Any ideas on what could be causing this? I've wondered if it has something to with the ways Safari loads plugins, or maybe the way it handles power-saving, but I've looked around in Preferences and haven't been able to solve the issue. 

 

Thanks
