Yeah, some kind of improved autodetection would be good,
but there are a couple of issues:
 (1) you really want to do it at runtime, not configure time
 (2) it's not uncommon for half these audio libraries to include
      backwards compatibility support for each others' APIs.
      Even though you can use PulseAudio's ALSA back-compat
      layer, it's a worse choice than using PulseAudio directly
      because it is (in my experience) buggier and adds latency.

Still, we could certainly do a better job than we do currently.
