I found this in Edit -> Plugins, but it's already checked. This appears
to control whether or not the Play, Stop, Pause buttons appear with the
WAV attachment. The problem is that when I click the Play button,
nothing (visible or audible) happens. If I uncheck it and restart
Evolution, then the Play-Stop-Pause buttons do not appear any more.

I also tried adding a custom command in Nautilus, but I'm  not certain
how to go about doing that (I do not normally use Nautilus much). I
tried using "play", "play %s", and "play -" as custom commands under
Edit -> Preferences -> Media -> Music Player, but it doesn't alter the
behavior of the Play button in Evolution for those WAV attachments.

I forgot to mention that this is with F12.
