Audio crackle on first sound (ofFmodSoundPlayer)

Hello. I’m using a vector of up to ten ofFmodSoundPlayer objects to play sound files. There’s an audio crackle on the very first sound I play upon running the program and on no sounds after that- even ones from the other players. I’ve tested it with playing different sounds first, so it’s not an issue of the sound file itself.

Is this an ofFmodSoundPlayer issue or something to do with oF accessing my audio drivers for the first time?
