I have just set up a Pi Music box.
It is working, and will play internet radio stations.
I have copied a load of existing music files to the memory card,. It recognises them and lists the artist, album name and track names when you browse to them, but it won't play them.
The tracks appear in the queue.
At the bottom right on the web interface it shows the triange "play" symbol suggesting it is not playing anything and inviting you to start it. If you pres the play button, it very briefly shows the "pause" symbol before instantly reverting to showing the "play" symbol again.
for reference, when it is correctly playing a radio station, that is normallly showing the "pause" button bottom right.
What am I doing wrong please?
