Soundblaster Z Series optical audio in?

[mrjoelabs]

I am trying to run a TV's audio via an optical cable into the soundblaster Z, then out analog speakers hooked up to the analog audio ports. All I am getting is buzzing... Anyone have any ideas?

Check the Windows Control Panel's sound panel and make sure the Optical Input port is the default Audio Input device. You also might have to enable a "listening" or "what you hear" option.
