OK, I'm having an audio issue. Playback using the rear green port is really muted. I've checked the cables and they're seated properly. In the Sound Preferences pane it is listed as "Internal Speakers". Strangely, when I plug in my earbuds to the front connector "Internal Speakers" changes to "Headphones" and the sound from that port is fine with the earbuds. When I plug the speakers into the front port it again switches to "Headphones" and they sound fine. There is also a "Line Out" which does not seem to function. With my other hackintosh, "Line Out" is the green port on the back, while "Headphones" is the green port on the front of the computer. I've never seen "Internal Speakers" on a hackintosh until this board/install. Any ideas?
