Hi,
Rern, thanks for your efforts and those of others who have made this project work so well!
I just reflashed to RuneAudio+R_e2-RPi2-3 and then did the update from the add-ons. Rune finds my library. Albums and webradio will load, but not play. Any thoughts as to why? I did not have this problem on the last version I used which I think was from Dec 2019.
(RPi3B+ HifiBerry Digi+ music is on an attached hard drive formatted hfs+, the drive is mounted by UUID)
