I haven't had time to mess with the settings too much yet, but I'm just looking for info from anyone experienced using this. This is for my AMD rig in my specs. I've been running the onboard Realtek audio just fine and now I would like to run it through the HDMI cable on my 4870, but it's not working for me so far. Anyone know the steps for a proper setup or where the instructions on doing it properly are located. Much thanks.
