Are you sure that Hi-Res streaming is possible with songs that have not already been purchased? As far as I'm aware, the only pure 24-bit/192kHz streaming service is from selected tracks on ClassicsOnline HD LL.
"Hi-Res API accessibility
To stream on Qobuz in Hi-Res quality, you must completed two conditions :
have purchased a product in Hi-Res quality.
You will the following find noted under purchase/getUserPurchases for each product: hires_purchased: true/false
be a Qobuz Hi-Fi Sublime subscriber.
You will the following find noted under user/login method , and in credentialparameters, a field named : hires_purchases_streaming = true
(users with any other type of Qobuz subscription have the field: hires_purchases_streaming = false)
