On the machine with Debian 8 the problem is still there, even after

On another machine with Debian8 I don't have the problem.
Then you should compare the installed gstreamer packages.
I did compare them and removed a package from the machine what does not
work. But it did not help.
I think the necessary package is gstreamer1.0-libav.
That's installed. Removing and reinstalling did not change the problem.
But it does work again. In the sound-settings I changed the volume of
the application, first to maximum, later to 70% how it was before (in
the tab "applications"). This did not change anything. After that I wend
to the "output" tab and then it worked, not sure why.
Maybe this can help somebody els
