Can you please check again if the URL is correct, 192.168.1.47 does not return a ping, it looks more like a home network.

[Marcin-Fenger]

It is local network. There are some mp3 files too and work well. It's not network issue.

Together with my firend Piotr We just have done some tests and I have got additional info. Flac radio streams works. Flac files without jpg works. Flac with jpg inside hungs the system. We try it on two independed systems and reason is the same.
