It seems Qobuz is not supported yet, although they have a web player, too:
Now that they have started in the U.S., it would make sense to add their streaming site as well, I think.
Adding help-wanted as this is behind a paywall.
OK, I have a free account at the moment enabling me to play 30 seconds excerpts (with CD specs, by the way, i.e. 44.1khz/16bit FLAC). Here is a screenshot showing their web player, so it doesn't look unusual with a standard playerbar at the bottom:

Theoretically Qobuz also offers internal scrobbling in their account settings which I have enabled, but as the 30s excerpts are right on the edge of not being scrobbled, I guess this is the reason why I don't see anything on my profile yet.
It's also available for me in demo mode, but it's enough to develop a connector for the website.
The last time I checked Qobuz it was inavailable for me due to geolocation restrictions.
Great, I wrote a Qobuz FAQ on the new support forum with two screenshots where to enable their internal scrobbling:

Thanks, will update the FAQ as well. :-)
