Play Audio Specific Speakers

I am making an interactive art piece and have come across an issue with audio. I am trying to make different interactions within unity trigger audio on specific speakers. So say there are 10 objects to interact with in an environment and someone interacts with item 5, i need the audio to go to speaker 5. The audio is dynamic so simple sound triggers to an external program isn't an easy option.

Is there any plugin or tool known that can allow unity to have audio be pumped to a specific audio channel at runtime?
