It should be under your Realtek HD audio manager under digital output, make sure thats set as your default output, not your 3.5mm jacks.

Realtek Digital Output Not Working

Answer 3

The only surround sound that a TV will output via optical cable is stuff it gets through the antenna. In other words, you can't plug your cable box, PS3, etc. into the TV with HDMI cables and expect to pass the surround sound audio out from the TV. In order to get surround sound from such external devices you must send the audio directly from those devices to your surround sound system.
