When using the Replay Mod, there are several sound glitches that are noticeable.
1. Sound not stopping when Paused
When you pause the replay, all sounds that were playing are not stopped. For example, if a song was playing, it would not stop even if you hit the pause button.
2. Slo-Mo Sounds not being slow
When lowering the speed in the Replay Viewer, the sounds will not become slower, but the sounds will keep running. For example, at the end of a game in Mineplex, the firework sounds would keep playing over and over at normal speed until the fireworks go away.
