Hasso Tepper has made /dev/audio a symlink to /dev/dsp.  DragonFly’s sound device hasn’t been /dev/audio in a while, but until recently in pkgsrc, applications that used audio would default to /dev/audio for playback.  With this symlink, they all should work - or at least not be directing sound to a nonexistent device.

This isn’t dramatic news, but I can never remember which device is the right one, and this fixes that little issue for me.
