Qml SoundEffect volume issue

I have SoundEffect object with a given volume value. But somtimes when I call play() for the first time, the sound is played at maximum volume. All subsequent calls of play() work correctly with a given volume.
This effect appears only under Linux, everything is fine in Windows.  This only appears when SoundEffect is in an object that was created dynamically using the incubateObject(). And volume value have binding with global property.
