In a sound's properties, the "Audio file" fields are bugged. UMT must restart for changes to show in the tool.

Describe the bug

In a sound's properties page, the Audio file property is visually and functionally bugged. If an embedded sound has never been assigned, the Audio file index number can be changed, but an embedded sound can't be drag'n'dropped into the adjacent field. After changing the index number to a valid embedded audio, the second field does not update, and the Play button claims there is no sound file

When editing a sound that has embedded audio assigned, the index number cannot be changed, but the second field allows drag'n'drop. However, the number and asset fields do not update, even though the embedded audio that was just now dropped in plays when Play is clicked.

Upon saving and restarting UMT, the Audio file fields show the correct Index Number and Embedded Audio, and the play button functions normally.

Reproducing steps

1. Go to a sound's properties (new or existing, doesn't matter).
2. Try to change either of the Audio file fields.
3. Note the lack of proper change.
4. Save and restart.
5. Changes now show as properly applied
