Been using RuneAudio for a year or more now with great satisfaction. Minimserver on Windows or Linux->BubbleUPnP on Android or Upplay on Windows10->RuneAudio on RPi3. Works fine including gapless playback.
Sometimes I use my Google Play account and BubbleUPnP on one of 2 Android phones to stream from Google Play directly to RuneAudio. This works fine most of the time, but every now and then skips to the next song in the middle of a song, which is maddening.
The Bubble developer has tried to find a solution and could only suggest changes to the MPD settings on Rune, but these don't seem to help.
Any suggestions welcome.
