DNT IP Diamond stopped playing after upgrade

I recently updated my Serviio installation from 1.4.1.2 to 1.9. I have multiple devices connected to the server that is running on a Gentoo Linux box, among these two DNT devices which - as far as I know - are based on the Reciva modules. The IPdio still works, but the IP Diamond stopped working right after the upgrade. I can discover and browse the Serviio server as usual, but when trying to play back audio files (any file - mostly files that worked before the upgrade), I just get the "spinner" and nothing playing. The debug log doesn't show anything that would suggest the immediate cause of this to me:

What should I try next to determine the cause and get this fixed?

yes that looks ok. File is served. Not much to be done unless you can compare the detailed log for version 1.4 with the same file.
