Audio output using Tascam/Cubasis

[homsap1]

I'm using a Tascam US-122 with Cubasis. I want my audio output from Cubasis to be able to go either through the Tascam (headphones) or through my computer (speakers.) As of now, it will only go through the Tascam. Is there some setting I can change to give me the option of outputting through my computer speakers also?

I had it set up to do that on my old computer, but my hard disk crashed and I had to start over, and it looks like I might have missed the step in setting it up again that would allow the speaker output.

Thanks for any help.
