Spark (vanilla/spider mtx) sound on expiration is tiresome

Both regular skill effect and with spider mtx, spark projectile makes sound when it expires. This sound effect gets very tiresome. Spark is scaled by cast speed. More cast speed means more noise from skill effect (on projectile expiration). It is particularly bad when game is set to low sound channel count, because it creates some sort of disharmony/stuttering. On default sound channel count - medium - it is just played too many times and it gets very tiresome - to the point when I just want to turn sound effects off just because of it or stop playing with the skill. It is not that bad when you play for a short amount of time, but after you play for longer, it starts to get really annoying.
