I'm certainly not opposed to using Pulseaudio in this case, since the audio
playback does not itself need to be low latency. Though the latency may be
more deterministic in a purely Jack based solution, in order to calculate
the delay to synchronize it with the lighting control.

I did not know about jack-plumbing. This looks like the most
straightforward to me and is probably what I'm going to use.

Thank you kindly for the great solutions. I was sure there were options,
but its been a while since I messed with this stuff.
