Can you add the section number and its title and possibly the version of the datasheet?

Rev 2.5 0x6D CLASSD_GAIN_1/ 0x6E CLASSD_GAIN_2: Left/Right Channel Class-D Driver Gain For DAC Left/Right Input (Step size is 1dB.) 00000 = Mute (DEFAULT) 00001 = 0dB 00002 = 1dB ... 11000 = 23dB 11001 = 24dB I will add it in V2

There is no audio output if Speaker volume is set above 25. According to datasheet maximum allowed value for the Speaker output is 0b11001 (25). So adjust this value with datasheet.
