You can get audio from a speaker the same way you get audio from a microphone, just replace the microphone with the speaker.

If you want be able to speak using the clients microphone, please explore the Video Viewer 2-way Audio sample.

This sample is standalone but you can use the same functions in the Smart Client environment in a Smart Client plugin.
