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

[DavidHB]

I originally posted this on the Linn Development forum, thinking that it was a problem with Kazoo. Having now discovered that I have essentially the same issue with Bubble DS Next, I am posting here as well.

Here are the relevant parts of what I previously posted:

'In the browse list [on Kazoo], I select Disc 1, and the Disc 1 page appears. It shows only the Album and '>> Hide Contents', not individual tracks or groups. If I then click on the album icon, I get the list of tracks or groups and can play or queue them normally. But at the intermediate stage (album only showing) I get the play/queue icons, but clicking them produces the white on red tool tip error message 'Audio not available'. Then clicking on the album item leaves me without tracks or groups at the lower level, and the error message when I try to play or queue the music. It is as though attempting to play the music at the 'Disc n' level switches off the recognition of the 'Disc n' contents.

While this is hardly a catastrophe, it is a bit unfortunate that the control point behaviour appears inconsistent to the user depending on the path he or she has followed through the browse tree. Also, it would be nice to be able to select a particular disc within a multi-disc album for playing or queueing.

... Bubble DS Next ... produces similar errors to Kazoo, but I have not yet been able to work out which sequence of selections produces errors and which sequence works correctly. The Error message when there is one is "no item was found in the direct sub-folders of the selected folder", which may be a clue as to what is going on.

All in all, there seems to be an issue in identifying the contents of the 'Disc n' container producing some sort of incompatibility between the MinimServer browse tree and the control points.'

I recall that this issue has arisen before and that there was a (so far as I know) inconclusive exchange on the technicalities between Simon and Bubbleguum. Since then, all the applications I have mentioned have moved on several times to new versions, but the issue persists.

Essentially, I think, I am asking that Control Points should recognise 'Disc n' or DISCSUBTITLE as a container in the browse tree. If I understand the Bubble error message correctly, it seems that the Control Point does not see the tracks within the disc container. Is it relevant that, as most of my music is grouped, all the immediate contents of the multi-disc albums I have tested are groups rather than separate tracks?

If there is anything I can do to identify the issue more specifically, please ask.
