DAC Volume Control is Working

Got the volume control working. I'm currently using two button switches to adjust the volume in the DAC. I've programmed it to go from -63 dB to 0 dB in 1 dB increment. You can find the code in the sidebar. The little module I made has 4 buttons. Two of them have not been enabled.
