I have the following setup:
- music-archive on my QNAP-NAS accessed via Twonky Server on the same NAS as UPnP-Server
- BubbleUPnP-Server running on the same NAS
- BubbleUPnP-App running on multiple Android-devices
- RuneAudio on RaspberryPi2 as UPnP-Renderer
Everything works fine here.
I can control the playlist from several android devices and if i turn of a control-point or leave the wifi the music still plays.
A very nice feature is the access to my music-archive via internet and tethering my UPnP-Server to other networks.
I don't use Tidal or Qubuz yet, so i can nothing say to your special problem. But I use Webradio-Streaming via BubbleUPnP-App to RuneAudio with XiiaLive which runs without problems.
After finding out
how to run Twonky togehter with RuneAudio on same device i just need to know how to run the BubbleUPnP-Server on my Raspberry. Then I wouldn't need the QNAP anymore!
