@support, I have tried reporting this issue numerous times as have many others. When adding an album from Qobuz, almost all metadata is being missed by roon. This information is clearly available using the Qobuz apps but not with roon. This is an easily reproducible general case and affects large numbers of Qobuz albums. It seems to me a very basic issue with the way in which the Qobuz integration was done.
It is difficult for me to understand what the point was in tweaking the search performance in build 416 if roon cannot find an album in the first place if it searched for the age of the universe because there is no basic metadata?
Here is another example (just an example, there are many, many others, it is an extremely common issue). This is how an album looks in Qobuz:
There is composer info, release info and the multi-part compositions have titles and are correctly grouped with identifying (and searchable) catalog numbers.
This is how the same album looks in roon:
Now there are no composer credits, incorrect release info, no composition titles, let alone catalog numbers, and no multi-part grouping. The album is to all intents and purposes invisible to roon on the most common search criteria (composer and/or composition) and unplayable in any other context than playing the album straight through (if you can find it).
In order to fix this, it requires over 30 manual edits and a lot of trial and error grappling with the undocumented way in which roon goes about parsing a multi-part composition title. So in case this helps anyone else, the canonical composition form of the English Suites is this:
English Suite, for keyboard No. 4 in F major, BWV 809 (BC L16): I. Prelude
The basic editing task is to add composer (Johann Sebastian Bach) to every track title instance and prepend the composition to every orphan part name. However, there are two commas before the colon (demarcating TITLE: PART) and roon will break the TITLE/PART on those commas instead of the colon to give:
for keyboard No. 4 in F major, BWV 809 (BC L16): I. Prelude
or if you remove the first comma
English Suite for keyboard No. 4 in F major
BWV 809 (BC L16): I. Prelude
so both commas have to be removed in your manual edit after which roon will automatically put the commas back to finally give
English Suite, for keyboard No. 4 in F major, BWV 809 (BC L16)
To a certain extent I can understand why tweaks to search performance was given priority in build 416. Performance issues actually made me stop using roon altogether for a while and start the process of going back to CD based replay (probably settling on a Luxman D-06u with a USB input so I can have a foot in all camps). But performance is only half a fix. There has to be something for roon to search on in the first place, so these ongoing systemic issues with Quobuz metadata integration really need to be addressed.
