DRC bypass/inline for channels 1, 2, 3, 4, 5, 6, 7, and 8 are mapped into registers 0xA2, 0xA3, 0xA4,
0xA5, 0xA6, 0xA7, 0xA8, and 0xA9, respectively. Eight bytes are written for each channel. Each gain
coefficient is in 28-bit (5.23) format, so 0x0080 0000 is a gain of 1. Each gain coefficient is written as a
32-bit word with the upper 4 bits not used.
To enable DRC for a given channel (with unity gain), bypass = 0x0000 0000 and inline = 0x0080 0000.
To disable DRC for a given channel, bypass = 0x0080 0000 and inline = 0x0000 0000.
