I observed a strange behaviour of Audirvana. If I first narrow the search in the library using a string (“Bach” in that example), the search indicates 254 albums matching that string. OK, that’s a lot but this is “Johann Sebastian”!!
Then, I select the albums item (“all”) and than wait, wait, … Nothing happened apart from a blank screen.
Usually it returns the first album in the list with the others available below. I checked that and it still works with other names (JSB not appreciated ? 
Maybe it’s the size of the list (254)?
What is clear is that even after an entire day searching for something I did not get anything else than a blank screen with a title saying it was looking for the previously entered string.
Application restarted after installation of an update. Problem solved.
