samples/Feature-Tutorials--Sound bug

There is a version bug in this sample

You have to replace the lines 56 + 57

self.slider = DirectSliderBar(pos = Vec3(0,0,.7), value = .50,
                    command = self.setMusicBoxVolume)

with that:

self.slider = DirectSlider(pos = Vec3(0,0,.7), value = .50,
                    command = self.setMusicBoxVolume)

Could someone please fix this bug in the cvs.

Hope it helps
Martin
