After powering on, the default volume is 0. Please increase the volume before testing. When describing, please specify the DTB you selected and the recommendation information from the web.

i tried on hg36 dtb, k36 dtb, clone type 1 dtb and the invert right joystick version, the original dtb that came with the console got yellow-marked on the dtb page with the dtb of type 1 (and invert right joystick) and hg36 marked as for testing and not guaranteed for full compatibility

Please run cat /sys/bus/iio/devices/iio:device0/in_voltage2_raw over SSH and check the difference in the readout value between when the volume button is not pressed and when it is pressed.
