You’re going to want to get into your audio settings and make sure your HDMI is set to send sound to your device.
If you are running Vista, right-click your speaker icon in the taskbar and select “Playback devices” from the menu. From there, a window will open and should list your audio devices. Highlight “Digital Output Device (HDMI)” in the list and hit the “set as default” button. Also, right-click and make sure the device is enabled.
