Audio Playing When it isn't Supposed to Be

I've noticed this for a few patches, but I keep thinking "oh, I'm sure they've heard of this by now" and waiting until the next patch, but alas, it has yet to be fixed.

1. When there is a Kog'Maw in the game, his passive sound will occasionally continue playing long after his death and even after his respawn in some cases at the spot on the map where he died.

2. Sometimes the inhibitor and nexus turrets will continue their laser-like sound effects when there are no targets around for them to even be firing their lasers at.

I've only noticed these bugs while on the team playing against kog, or against the turrets, if that makes a difference.
