I understand that the voltage of SPKVDD is greater than or equal to AVDD, but what difference does it make in the operation of this device when SPKVDD is 5V and when SPKVDD is 3.3V?

Thanks for the answer.
Am I correct in understanding that the voltage/power of the speaker drive is determined by the voltage of the SPKVDD, which will affect the maximum volume of the speaker?
If there is a difference in maximum volume, how much difference is it?
You can refer to the data sheet Figures 4-10 and 4-12. These show the output power performance for different SPKVDD levels: https://www.ti.com/lit/ds/symlink/tlv320dac3100.pdf#page=15
