Volumio as renderer

[SpruceFan]

I have MinimServer/Streamer running on a Synology NAS and also on an headless Raspberry Pi 3. For a control point I use either Linn Kinsky (always works) or Kazoo (better GUI, but often fails). I have two renderers: an Auralic Aries Mini or another headless Raspberry Pi 3 running Volumio with an attached USB DAC. This streaming file:

#EXTM3U
#EXTINF:-1,[BBC] BBC Radio 3

Works well on the Aries from either implementation of MinimStreamer. It will not play on the Pi running Volumio. Streaming directly from Volumio using a browser window on my desktop works fine. Clearly I am doing something wrong with getting the streaming URL to Volumio.
