The stream doesn't work 

If the stream does not start after selecting the language, check the following:

Are both Javascript and Adobe Flash Player up to date? In addition, you should check whether a firewall is active and, if necessary, set it so that it does not block or slow down data traffic to the sooner.de server.

If you are using a public network, for example at a university, a library, or a hot spot, or if you are trying to stream from work, it's possible that these facilities or your workplace block streaming on their networks.
