The NAU8822 datasheet register map puts DACOS and ADCOS at bit 3 of those registers. In R14, bit 5 is inside HPF[6:4], which the High Pass Cut Off control owns. So turning on ADC oversampling changes the high pass cut-off, and the oversampling bit cannot be set. In R10, bit 5 is reserved, so the DAC switch has no effect. Use bit 3 for both.
