I have my computer hooked up to a 5.1 surround sound system (which system it is is irrelevant) via optical cable and my computer won't play 5.1 sound.

I recently installed Windows 8 on this computer, when I was running windows 7 the 5.1 sound worked just fine and I haven't changed any settings on the sound system.

When I was running Windows 7, the screen below used to have a Dolby Digital tab where did the tab go?

There is Dolby Digital on the screen below, and when I press the Test button, all 5 speakers and the subwoofer work.

However, I can't get it to work with any actual applications. For example, this 5.1 test file only plays in Stereo (tested and working in Windows 7).

Is there a driver I'm missing or a setting I need to change that I keep missing?

My computer has the Gigabyte GA-880GA-UD3H Motherboard, I'm using the onboard audio, and I'm running Windows 8 64-bit.

It doesn't look like Gigabyte/Realtek have official Windows 8 drivers yet. You can download the Windows 7 drivers here and use them.
