No sound

Hi,

Sound works in any application, like VLCs, but not in MuseScore. I have read several sound problem posts, but the given solutions do not work for me.

My System...
* KUbuntu 16.10
* MuseScore 2.0.3
* MuseScore configuration: "PulseAudio" as output selected, Synthesizer "FluidR3Mono_GM.sf3" available

Older MuseScore version worked for me with Ubuntu 12. As far as I remember, it does not work anymore since the update to Ubuntu 16.10.

To fix the problem, I have tried to...
* make a revert to factory settings
* uninstalling MuseScore, removing the folders "~/.config/MuseScore/", "~/.local/share/data/MuseScore/" and reinstalling MuseScore.
* changed the output configuration to "PortAudio", "ALSA-Audio" (default, 48000, 3, 1024), "JACK-Audio-Server"

...but nothing worked for me.

Has anyone an idea?

Thanks
