I'm using safari (and I've tried with latest webkit) and I get no audio on several websites, such as youtube. I've tried multiple videos on there and I get audio just fine out of iTunes and video locally on my machine, but not on the web.

I've also confirmed that the audio on my machine be coming from internal speakers...help.

Launch Garageband once. That should fix the issue.

If you don't have Garageband you need to Google for the correct settings to make manually in the Audio-MIDI-Setup utility.
