7.30 Volume Registers (0xD1–0xD9)
Channels 1, 2, 3, 4, 5, 6, 7, and 8 are mapped into registers 0xD1, 0xD2, 0xD3, 0xD4, 0xD5, 0xD6, 0xD7,
and 0xD8, respectively. The default volume for all channels is 0 dB.
Master volume is mapped into register 0xD9. The default for the master volume is mute.
Bits D31–D12 are Don't Care.
