Halo PC can play sound tags containing uncompressed PCM data, but for whatever reason, Gearbox (or Bungie?) completely botched this and added a check that specifically disables this functionality.
If the sound format in the base struct of the Sound tag is set to "Uncompressed" then the sound tag will not work. However, if it's set to anything else, then it will work even if the sound, itself, is actually uncompressed.
