it seems there is something wrong in how the sample rate is exposed in Lumïn app playing from Qobuz.
In this example the track “Tell me” from Ray Vaughan “Texas flood” is shown to be 24/192
but as I’m using HQPlayer Embedded there I can read 24/176.4 as well as in the original Qobuz app (iPadOS)
As Lumïn app should read the track/playlist informations from Bubbleupnpserver I think the issue should be in Bubbleupnpserver
