Hey everyone – we were not ignoring this request, and we actually spent a bunch of time getting this right with Qobuz before we released our integration in Roon 1.6.
In order for volume leveling to work in Roon, Qobuz needs to analyze each file in their service and provide the leveling data to us. This is a big project, and we know that Qobuz has been working on processing their music catalog over the last year.
After seeing this feedback recently, we did some investigation to get a sense of how much of the Qobuz catalog includes volume leveling data. And… we found a bug 
So, as of yesterday we have a fix live on our servers and volume leveling data should again be used in Roon when it’s available. 
Note that it may take some time for these changes to filter down to content that’s already in your library – you can always select “Re-Identify Album” from the Edit menu to retrieve updated metadata from our servers, but this will happen automatically for your library over the next few days.
If you see tracks outside your library that do not include volume leveling data, it means that Qobuz has not provided us leveling data for that track. As mentioned, they are working through their catalog and you can feel free to reach out to them directly for updates about their progress.
Thanks all!
