Wwise SDK 2015.1.9

Start streaming the first part of all steamed files referenced by an event into a cache buffer. Caching streams are services when no other streams require the available bandwidth. The files will remain cached until UnpinEventInStreamCache is called, or a higher priority pinned file needs the space and the limit set by uMaxCachePinnedBytes is exceeded. The amount of data from the start of the file that will be pinned to cache in is determined by the prefetch size, which can be set via the authoring tool and stored in the sound banks, or via the low level IO. If this function is called multiple time successively with the same event, then the priority of the caching streams are updated. Note however that priority is passed down to the stream manager on a file-by-file basis, and if another event is pinned to cache that references the same file but with a different priority, then the first priority will be updated with the most recent value. If the event references file that are chosen based on a state group (via a switch container), all files in all states will be cached. Those in the current active state will get cached with active priority, while all other files will get cached with inactive priority
