I finally got my rpi4 up and running and installed the latest version of Runeaudio v e 2 with a Hifiberry DAC +Pro. I have my music on an USB flash drive. It sees the drive, but I can't load the library. The system comes up, I can play a song, but I can't get it to create the database so that it can access all music. I don't know if I'm doing something incorrectly, or it's another issue. But I'm getting frustrated not only with the issue, but the lack of intuitiveness and comprehensive documentation.
I appreciate any assistance. I want to enjoy my music, but I'm not going to add it manually one song at a time.
