Summary

Setting the Sounds field in the sound_component with []sound_wave coming from editables causes the sound_component to not play audio when Play() is called. Hardcoding the array with precoded sound assets will play in the world.

What Type of Bug are you experiencing?

Assets

Steps to Reproduce

  1. Create a new MMS asset
  2. Create a new sound_component using the MMS asset in verse
  3. Set the Sounds to a new array of sound_wave coming from an editable
  4. Add the component to a character entity
  5. Call Play() on the sound_component

Expected Result

The sound_component should play a random sound from the given array of sound_wave.

Observed Result

The sound_component does not actually play, printing the lenth of the array does return the correct number of elements, but it does not actually play a sound. Hardcoding the array does make the sound_component play.

Additional Notes

This is some annoying behaviour as it limits dynamic use of sounds through editables
