rear speaker and handset microphone are always used and handsfree & standard speaker doesn't work

steps that reproduce the problem:
0. launching CSIPSIMPLE on the screen
1. clicking to start an outgoing call or to receive an incoming call
2a. having a normal conversation
2b. toggling the speaker button
2c. connecting the handsfree earplugs+mic

2a : I expect to get the sound on my ear
=> that's not the case, it come from the loud speaker at the back

2b : I expect to toggle the sound between the earspeaker to the loud speaker
=> that's not the case, it comme anyway from the loud speaker at the back but 
at the moment I toogle, the output and input of audio are stopped for half a 
second and the "bip" coresponding to a touch of a touch go through the normal 
earspeaker

2c : I expect getting the CSIPsimple sound by the handsfree earplugs and record 
my talk through the handsfree mircophone
=> that's not the case, it come anyway from the loud speaker at the back and 
record via the handset microphone but at the moment I toogle the speaker button 
(step 2b), the output and input of audio are stop for half a second and the 
"bip" coresponding to a touch of a touch go through the handsfree earplugs.

I'm using :
- Samsung Galaxy Young duo
- Model GT-S6102
- Android version 2.3.6
custom ROM & kernel

Usefull other informations :
- before to start a call (incoming or outgoing cf step 1) the sound work 
correctly e.g when I click on the phone button in CSIPSIMPLE to start a call it 
emit a "bip" in my handsfree or in the earspeaker indicating I touch a touch on 
my screen.
- when i updated skype in June-July 2013, i got exatly the same probleme with 
Skype. Then they fixed it on the next uptdate or the next next, because I saw 
that some others complained too (with another android and phone). interesting...

Thank you very much
