I was playing tinker(with BoT) on Radiant, and I teleported back home. I then dragged my mouse on the map to the far bottom left corner.

The teleportation sound started over from the beginning.
The sound ended when the teleport finished, but it ended in the middle of the sound effect, instead of replaying completely.

This bug is especially noticable with the new Boots of Travel Mk III, because the sound is very distinct.
