When for an external audio source dynamic compression is enabled (bit COMP is logic 1) the MSL setting
controls the compression ratio. For default 2 : 1 compression MSL = 01 is used; see
When for an external audio source dynamic compression is enabled (COMP = 1) the MST setting controls
the compression range. For default full compression MST = 7 is used; see
