[ale] Multi-Channel Whole House Audio

[Richard Bronosky]

I think there is a flaw we're overlooking. Why would you use multiple
sound cards? There are 2 approaches I would consider. The first is a
tiny Arduino-like network device in each room. It could be connected
via ethernet or WiFi. The second option would be a USB audio devices
that can be daisy chained with hubs. I would be reluctant to do the
D/A conversion at the head unit. I would pursue the network connected
approach.
