Perhaps you are missing the mp3 decoder gstreamer plugin. Our troubleshooting page suggests running sudo mopidyctl deps to see what’s installed, that would help understand.

You normally don’t need it as there are other decoders available. Do you have the exact same error as originally posted? Let’s see your deps please.
