@Mauricio
do you find the right way, I have the same trouble.
Solved:
jack 4 pins male:
from cable first contact is ground, second is for video, 3eme and 4eme for audio
jack 5 pins femele on pi pc (plus):
from outside: first contact left and right is ground soldered on board in left and right (will be in contact when male jack pluged in), second contact for video soldered on board on the right side.
When plugged, the right jack make the job and there is no "continuity".
