Post output of

aplay --dump-hw-params -D surround40:CARD=Live  any.wav

Seem pulseaudio does not support MMAP_COMPLEX and fallback did not work as
expected

If device 0 of your ct4832 can pan stereo to both jacks and volume of rear
jack is controlled by wave surround playback volume control

The easy hack is to use hw instead of front for stereo  if your green jack
is not working

[Mapping analog-stereo]
-device-strings = front:%f hw:%f
+device-strings = hw:%f
channel-map = left,right

The common problem of front jack fail to work is  Pulseaudio does not
ensure pcm playback switch is always ON

Also try patch to force pcm playback switch to always ON
