Stream hangs up after couple of minutes

When streaming from windows 10 laptop to a Raspberry with Kodi (based on OpenElec version 15), then the sound will stop after a few songs.

Then I close SWYH in the tray, but actually it would not close until I shut it off with the task manager. Only after shutting down the SWYH process and restarting the program I am able to set up a new stream to Kodi.

Kind regards
Thomas
