When changing clock ratio or sample rate it is recommended that zero data (or near zero data) be present on SDIN
for at least 10 LRCK samples before the change is made. During the clocking change the DAC outputs will always
be in a zero data state. If no zero audio is present at the time of switching, a slight click or pop may be heard as the
DAC output automatically goes to it’s zero data state.
