Higher resolution is possible, one LSB step results in a gain step of about
1/8 dB.
With positive bass settings clipping of the output signal may occur. Therefore,
it is not recommended to set bass to a value that, in conjunction with volume,
would result in an overall positive gain.
The settings require: max (bass, treble) + loudness + volume ≤ 0 dB
