Hi Benoit, Yes sir it looks like your going to need to change a cable. If the microphone is not working when speaker is on, then check for damage to volume headphone jack flex.This flex cable also has a microphone attached to it. This cable is probably damaged and needs to be replaced.

Heres a link to the guide to replacing that flex cable:Here

& Heres the part link so you can buy the part.

Hope this works for you my friend!

Good Luck!
