A wagering game system and its operations are described herein. In embodiments, the operations can include determining audio playlists from a plurality of independent wagering game applications (“applications”). The audio playlists can include multiple sound content that is activated contemporaneously on a wagering game machine for each of the applications. The operations can further include determining sound classes assigned to the sound content and determining, from prioritization rules, priority values for the sound classes. The operations can further include comparing the priority values and generating sound balancing priorities for the sound content based on the comparison of the priority values. The operations can also include dynamically balancing the sound content, as presented on audio production devices, based on the sound balancing priorities.
