[1.7 BLOCKING LIVE] A Nightmare in Candyworld: Almost none of the music plays but almost all of the dialogue does

Verification builds: 1.7.0.2 R7 Beta 21

Summary: For the most part, almost none of the custom music successfully plays in A Nightmare in Candyworld. However, almost all of the dialogue does. It is worth noting that there is no distinction between music and dialogue in the sound_definitions.json for this map as they are both set to play on the "ui" sound category. Therefore, I suspect the failure to play may be related to the length or size of the sound files as music is always longer. The longest sound files in the map are the music pieces and the narrator intros to each chapter. Naturally none of those work. An example of a music piece that DOES work is the musical outro that plays when Sugar Bones is defeated (located in sounds->custom->bossbonesend.ogg) which is only 10 seconds long. However, strangely, drone.ogg (located in sounds->custom) DOES work despite it being 1 min and 15 seconds long. In addition, sewer.ogg (located in sounds->custom) also works despite it being 1:01 long. So I'm not sure why it is so consistently working for dialogue but breaking for music.

Impact: A Nightmare in Candyworld relies HEAVILY on sound and music and this bug significantly hampers the intended experience.

Repro Steps:

1. Download A Nightmare in Candyworld from the store.

2. Create the world

3. Select a difficulty by pressing a button twice.

4. Move into the lobby and press the button twice to start the map.

5. Observe the issue. If you wish to further observe the issue, continue playing the map (note that there will be asserts during chapter intro sequences including the start of the map due to an unrelated bug)

Observed Results:

**99% of the dialogue plays properly.

99% of the music (including "narrator + music" files) does NOT play properly.

Expected Results:

 

All sounds play properly.

Screenshots/Videos attached: No

Notes: This is almost certainly an encryption issue because when running from the local template version all sounds work properly.

Regression Build: 1.6.0.8
