Seems like its bugged, at least with Creative Alchemy+X-fi on Win10. You can barely hear the waterfall in the first level and when you fall in water (for the first time) you don't hear the sound of water when you turn your back on the river

I didn't notice any bugs when using DSOAL a few years back; have you tried that?
Hmm, i will try it..
