It's often difficult to tell when the sugar that's been added to a cup of coffee or tea has completely dissolved.

If the sweetener released bubbles and made noise as it dissolved, though, it would be simple to know when it was finished dissolving, by looking for bubbles or listening for fizzing.

Pop Rocks candy, if it didn't have flavoring, would be an ideal solution. Or, the flavoring might be something coffee-appropriate, such as hazelnut, amaretto, vanilla, irish crème, chocolate, and so on.

Fizzy powdered coffee whitener might also be a possibility.

Make the sweeteners shaped like tiny ships with tiny bands on board to play Taps, Nearer My God to Thee, or some other appropriate tune while the ships slowly sink.

Tiny WW2-era ships - aircraft carriers, cruisers, destroyers. And kamikaze planes made of sugar ...

It should be easy enough to make any particular shape, but sadly, the sound is probably limited to fizzing/popping.

Making a sweetener that quacks or moos may require magic.

well you need something that can be made to vibrate at a preset series of frequencies. This has been done with magnets but a cup of hot coffee represents quite a bit of energy to vibrate something. Also there must be some nontoxic chemical that heats up in contact with water. That can make a whistle depending on the shape.

That covers many bird songs but not a quack or a moo. So next put a fluttery bit of rice paper in the whistle throat. I think that'll quack.
