Reverted: dc87ef1a34b6 Parameter distMax depends on fixed values in sheets and other code. Using this to switch between rolloff and minimum sound is likely causing the glitchy sound volumes of background sounds. Must be fixed in whatever code is using too large value of distMax instead, and not here.
