Thanks, this was of course the solution. I'd suggest that gstreamer1.0-alsa was a dependency of ubuntu-restricted-extras. Assuming that pulseaudio is installed is all right for the standard Ubuntu installation, but not, for example, for Lubuntu. I'd expect that other Lubuntu users run into the same problem.
