Does your computer, or attached soundcard(s) have capacity to drive three outputs at once? If it does I think you'll need to tell whatever software controls that hardware where to take audio-data from. Maybe 'sox' can direct audio to multiple channels, but I think you will need to tell sox which hardware devices to use. The section of the sox manual, page 3, "Playing & Recording Audio" might help. -- Jeremy Nicoll - my opinions are my own.
