Minim stream being throttled on QNAP NAS ?

BubbleUPnP knows nothing about masters/slaves all it sees are multiple renderers. Once you've chosen a renderer BubbleUPnP simply tells it what to play and it's then down to Sonos to handle all the stereo/multiroom synchronisation.

In the BubbleUPnP Server Media Renderers configuration page each of your Sonos units will be listed. For each of the renderers you need to:

• enable 'OpenHome' (the functionality to hold playlists)
• enable 'Gapless playback'
• set 'Decode audio to PCM for' to 'Never Use' (this is optional but I prefer to be in control of any decoding/transcoding that's taking place).
  

Once you've done this you'll see duplicate renderers in the BubbleUPnP app:

• Lounge - Sonos
• Lounge - Sonos (OpenHome)
• Kitchen
• Kitchen (OpenHome)
  ...
  

The best thing to do at this point is hide the non-OpenHome renderers in all of the BubbleUPnP app installs (More > Settings > Configure devices visibility) so there's no confusion. If some units are always paired/multiroom it's probably best to remove those slave OpenHome renderers at this stage too - or even better don't create them in BubbleUPnP Server in the first instance.

When you enqueue a track/album to an OpenHome renderer it's actually held in BubbleUPnP Server, rather than in the app itself. As such, if you select that renderer on another device it will pull the queue from BubbleUPnP Server and you'll be able to manage the queue from both.


None of this changes the fact that you still need to play to the master Sonos renderer for playback to work correctly.

Hope that makes sense.
