Comment:

 This is unfortunately a bug/feature of the Bink file format.

 There is no information in the .BIK file describing which audio stream
 maps to which speaker. The mapping is done manually by the game
 programmer, and varies from game to game.

 Quote: "''For 5.1 or 7.1 audio, you simply mix multiple stereo or mono
 input files into different Bink tracks IDs, one at a time. These separate
 input files are called "stems" in video editing software. '''Once you have
 mixed all the input files into Bink audio tracks, just tell your
 programmers the layout of the Bink tracks (like, track ID 0 is front left-
 right, etc).''' The programmer then directs the Bink audio tracks to the
 proper speaker at runtime.''" --
