0x93—Bits[7:0], Maximum Bit Rate
For compressed audio only, when this value is multiplied by
8 kHz, it represents the maximum bit rate. A value of 0x08 in
this field yields a maximum bit rate of (8 kHz × 8 kHz = 64 kHz).
0x94—Bits[7:0], Speaker Mapping
Bits[4:0] define the suggested placement of speakers. Bits[7:5]
are currently not available. See Table 23 and Table 24.
