Audio lag with SPC sound effects

[Void]

Recently WohlStand updated SDL Mixer X to allow support for SPCs to be used as sound effects. Although this works well, upon testing a level in the editor with these custom sfx, the game takes a few seconds to load and the audio begins sounding choppy. Wohl stated that this is the program loading the sound effects and that there's no real fix to it. However, loading the episode alone will load the custom sound effects once until the episode is exited out of, meaning there's no level lag or anything.

Basically, could you find an alternate way for sound effects to load when testing levels them in the editor so I don't have to wait a bit to test a single level? Perhaps associations could be loaded from the GPK file upon loading the level editor?
