S/PDIF allows digital audio data transference between two devices without any loss in signal quality. Unlike pure analog formats, audio data over S/PDIF is passed on directly to your audio receiver for processing. This transfer method allows you to send industry standard formats such as Dolby Digital and DTS directly to your receiver to provide multi-channel audio without the need for matrix-level converting. Your Gigabyte X38 DQ6 motherboard is equipped with an S/PDIF port on the onboard Realtek HD audio chip. If you have a receiver capable of negotiating a digital signal, you can take advantage of the high quality multi-channel audio formats by connecting an S/PDIF cable.
Instructions
1. Connect the S/PDIF optical cable to an available "S/PDIF In" port on the back of your receiver. Take note of the input number labeled at the top or bottom of the port.
2. Connect the other end of the S/PDIF cable to the "S/PDIF Out" on the back of your computer. Grab your receiver's remote and select the appropriate input number.
3. Go over to your computer. Click "Start" and open "Control Panel." Once in the Control Panel, click "Hardware and Sound."
4. Click the "Sound Effect Manager" icon. This loads a Realtek user interface on your screen. Click "Speaker Configuration" and then click "6 or 8CH + S/PDIF."
5. Close the Realtek interface. Press the "Windows" and "R" keys simultaneously. Type "mmsys.cpl" in the Run box and press the "Enter" key. This loads a Sound Properties window.
6. Double-click "Realtek Digital Output." This opens a new dialog window. Click the "Supported Formats" tab. Click in the box next to the formats your receiver supports. If you are unsure, highlight the format and press the "Test" button.
7. Click the "Apply" button to save your changes. Press the "Windows" and "R" keys simultaneously. Type "Wmplayer" and press the "Enter" key to open Media Player.
