[Lab] A Question About Multiple Audio Devices

I have used a little cheap USB sound card ($10) with a Raspberry Pi. It has
mic and speaker ports. It shows up as a sound device in Linux. I imagine
you could use as many as you liked with a powered USB hub, although I'm not
sure if they would always number themselves in the same order when booting.

This might be overkill though if you only ever need one mic or speaker
working at a time. In that case, one mic/speaker jack + an couple 8-way
switches of some sort (what would you call those?) would do the trick.
