BTW , if ymf7xx (DSP) only accept 16 bit digital PCM data and output to 18-20 bit AC97 codec ,
The DSP uses more precise values internally.
DSP use more precise values internally only increase the number of step ( dB per step is much finer resolution , the dB range is limited to the number of bits of the input digital signral and output digital signal which pass through ac97 link
There seem to be no hardware can provide infinte dB range
