Why am I not hearing any audio from my timeline?

I am not getting any audio. I get the warning sounds that Edius makes, but I am not hearing any audio when I play the video from the timeline, even though I see that their is audio from the waveform and the audio mixer. What gives?

What is probably happening is that your speakers are plugged in to the audio output of your computer, and you have chosen the project settings of the Canopus board of your system. Try plugging your speakers into the audio out of your Canopus board.
