This almost sounds like another face to the "end of the sound is
clipped" problem that Newpcm has always had. It used to be that on very
small files (interface sounds and whatnot, you just wouldn't hear
anything. I guess the new card sends an interrupt back when it's done
playing the sound or something that tells FreeBSD that it can let the
program using the soundcard finish shutting down.
