Prepares or unprepares game syncs synchronously.
The group and game syncs are specified by string (refer to 概説 for a discussion on using strings and IDs). The game syncs definitions must already exist in the sound engine by having explicitly loaded the bank(s) that contain them (with LoadBank()). A request is posted to the Bank Manager consumer thread. It will resolve all dependencies needed to successfully set this game sync group to one of the game sync values specified, and load the required banks, if applicable. The function returns when the request has been completely processed.

AK_IDNotFound: At least one of the event/game sync identifiers passed to PrepareGameSyncs() does not exist.
AK_InsufficientMemory: Insufficient memory to store bank data.
AK_BankReadError: I/O error.
AK_WrongBankVersion: Invalid bank version: make sure the version of Wwise that you used to generate the SoundBanks matches that of the SDK you are currently using.
AK_InvalidFile: File specified could not be opened.
