Control Points do not recognise 'Disc n' as a container

On the album display on the library page in Bubble with either Disc n or DISCSUBTITLE containers showing, it is possible to select a container, but any attempt to play or queue the tracks will produce the error message "no item was found in the direct sub-folders of the selected folder". At that point, Bubble, like Kazoo, seems to lose the ability to navigate down the browse tree and find the groups/tracks in the disc container.

If, at the album level, I open (short tap) the disc container without selecting it, I get an album icon which in turn can be selected to reveal the groups/tracks, which can then be played normally. If, rather than playing the tracks, I navigate back up to the album page and select the disc container at that point, the tracks do queue and play (presumably because Bubble has cached the nodes of the browse tre that it has actually seen).

From all this, I conclude that the core problem, of the Control Point not recognising the tracks in the disc container at the album level of the browse tree, is common to Bubble and Kazoo. I hope that this additional information is helpful.

I can reproduce this problem.

Supose you have the following tree in an album

Code:

>> Disc 1
    >> Hide Content
     "Album title"
             track 1
              ...
             track N

If in BubbleUPnP or BubbleDS you try to play folder ">> Disc 1", BubbleUPnP will load all its content recursively, loading ">> Hide Content" first and "Album title" second. The action of browsing ">> Hide Content" does what it means: it hides content of "Album title" when that folder is browsed. This results in 0 items being found and the error message dispayed you mentionned. I suppose this is a MinimServer workaround to avoid track duplicates in recursive browses from Control Points.

If you enter "Album title" manually before playing ">> Disc 1"", there are items founds since Bubble will use the cached tracks from the manual browse.

There's no solution to that problem with how "Hide Contents" work. The only solution is to browse manually to the "Album title" folder and play from there.
