This is consistent with the LUMIN app having an out-of-date cached URL and Kinsky having the correct current value of the URL.

Based on feedback from Lumin support I reloaded the library from the Lumin control point app. This worked. Previously I had restarted and rescanned the library from Minimwatch, Thanks for your help

Thanks for that Simon. I think I understand now.
So control software, like Lumin, Kinsky, Kazoo will tell my streamer, i.e. write on its playlist, not only where a file is on a NAS, but what sort of file it thinks it is. And transcoding has to con it so that the file is treated properly. Cunning....

Lumin is different, because it, essentially, re-indexes the library for its own purposes; when you access the Lumin tabs, you get the Lumin library, not the MimimServer index, which is only available via the 'Folders' tab (so 'folders' in Lumin does not mean the same thing as in, for example, Kazoo). As I understand Simon's advice, changing the stream.transcode property changes the URL offered by MinimServer, so Lumin has to upload and index it all over again. A far from ideal design concept, IMO. Other control points cache some information (especially album art), but they use MinimServer's indexing for browsing, searching and selection.

The point about transcoded files is not that the control point has to think it is something other than what it actually is. From the perspective of both the control point and the renderer, the transcoded file is the real thing. When Bubble tells me that my DSM is playing a WAV file (rather than the FLAC that is actually stored in the library), that is exactly what it is doing. No need for any trickery at all. But, I agree, it's still very clever.

Thanks David - as ever, very helpful and clear..... The reason I persist with Lumin on my old iPad is that the Linn softwares are just too slow.

I am using the Lumin app, but always on the folder structure (having 4000 albums, I prefer this to bad tagging)

I confirm that everytime I change the transcoding, I don't need to reload the entire library. The transcoding is always performed according to Minimserver parameter

There are pros and cons to Lumin's approach. I prefer their approach. Once you have a stable set up (i.e. you are not constantly retagging songs), Lumin gives you a more responsive app, especially on older equipment. The downside is of course when things are not stable. Choices, choices...
