Audio levels

As I am upgrading my ubuntu distro, I am killing time with MuseScore, on my other machine.
I am finding out that the audio from musescore is far lower in level than my other sound making software(s).
I have turned the volume up in the play panel to max, I have also sdjusted the sound system in my computer foer musescore to a higher level than other sounds (windows sounds) still the musescore audio is like 25% of the other sounds.
Any ideas?
