Chunks of audio are read from the disk using instances ofIAsyncReadRequest, similarly to your texture streaming and geometry streaming systems. Because of this, you can prioritize audio chunk loading above or below other streaming systems in the engine using the cvarau.streamcaching.ReadRequestPriority. This value can be set from 0 to 4, where 0 is the highest priority and 4 is the lowest. The default value for cached audio streaming requests is2.
