Always gives me a "Oooops, an internal error has occured..." when using default playback device.

Here is the log:
Screamer.Core.Services.Dispatcher.DispatcherException
An error occurred while handling a message of type ConnectToStation

Inner exception

System.InvalidOperationException
Could not start playing stream

Plays fine with S/PDIF pass-through or BT headphones though.
