    At the moment pigpio on the Pi4B is experimental. I am not -sure if the DMA channels being used are safe. The Pi4B defaults are -primary channel 7, secondary channel 6. If these channels do not -work you will have to experiment. You can set the channels used by -the pigpio daemon by invoking it with the -d and -e options, e.g. -sudo pigpiod -d 5 -e 8 to specify primary 5, -secondary 8.
