I’ve tried Steve Reich - Reich Richter and it plays normally here.
On both my MacBook Pro and MacBook Air. Each running on macOS 12.4 / Audirvana Studio 11301
Thanks for the helpful suggestions both - for some bizarre reason Studio had connected to an ancient Qobuz account (I did not have to login when I installed it, which did puzzle me). Aurivana 3.5 was connected to the correct one - hence the 30 second tracks on Studio.
Now I can enjoy the music! When I trialled Studio on launch, I was unimpressed, but a year or so down the line, the audio difference is noticeable.
