Hi,

When I build the Unity game can still hear some crackling/clipping, but it plays nice on the Editor. Do you know why?

Crackling is usually a performance issue, on iOS this could be due to resource limitations that you aren’t facing on your computer. Are there any warnings or errors in the debugger?  
I recommend connecting the profiler and looking out for high CPU and memory usage. Is it regular crackling or does it only happen occasionally?
