@seansong Yes, have tried latest firmware, it helped with the really bad volume (altho, if you touch the volume on your phone after you hit play, it still defaults to MAX)
But the main issue I have, is it isn't quiet enough. When I have other speakers on really low, it is nice a soft. With the cube, if I have it on low in a baby room with no noise, it still seems very loud. I need to be able to turn this down so low you can only just hear it.
Can there been an update to the app to allow more precise volume control, not just the physical knob. Never seen it before and it would be pretty cool to customise your own volume levels.
Also like @TaaviTamtik I would like the start up sound to be removed or reduced. If you turn it on when you first walk into baby room at night, it plays REALLY loud!
