Output channels are assigned to the front left (L), front right (R), front center (C), LFE, rear left (Ls), and rear right (Rs), in the order of the
smallest channel number. (Channels that are not used will be skipped.) When the single rear (S) is to be used, the rear left (Ls) is assigned.

Audio set as Ch1 in the sequence settings is encoded as L, and audio set as Ch2 is encoded as R.
