Mac Mini Digital Audio Output

I'm trying to connect my Mac Mini to my Vizio flat screen TV, and am having trouble with the audio output. I've connected the video through HDMI, but am trying to connect a wire and plug from the mini to the TV without success for the audio.

I first checked this online recommendation

and followed the directions....

but I can't see the selection for "Digital Audio Output - built-in device" mentioned there and on the apple site below

any suggestions?

Is the fiber optic cable plugged in and connected to a working device? I don't think you can select audio output devices that are not connected.

Thanks Chris. That's a good point and I believe it is connected. Will try rebooting my mini once connected to the audio to be sure....
