If this is the case, can we skip integrating sndfile-play, at least
until it honors Sun Ray?

I was just talking about marking them Obsolete, not actually removing
them. I don't think we'll be able to actually remove them anytime in my
lifetime. :-)

I'm inclined, from the materials presented here, to recommend against
integration of the sndfile-play utility, but to recommend *for*
integration of the library and the audio conversion utility.
