When using a Spatial Audio Source component on an audio source, using "PlayOneShot" will occasionally ignore the max distance set for the component, sometimes playing the whole clip while other times cutting off the clip after playing really quickly. I'm personally using this for collision audio for physics objects, so randomly hearing blocks clanking together from across the map is rather obnoxious. I've set up a quick demo for this, simply chuck the objects as far as you can and they'll occasionally make sounds despite being far out of it's max range.
