Welcome to MinimStreamer!

[retraite]

Have now tried Radio 3 using the info you supplied and transcoding aac:wav. The stream ran for just over 50 minutes before stopping. Previously the stream stopped and would not restart, this time restart was continually attempted and successful for a moment before it dropped again. After pressing stop and play in Kinsky, the stream has now re-established itself properly and been running for nearly 10 minutes.

I'll keep experimenting
