Hi @Defnesp, sorry to hear about this. 
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
Is there any error message in the device, or is the sound played through the speakers when you have the headset connected? If you haven't tried with another headset, I would recommend doing so, just to make sure that it's not the headset that is the culprit.
Let me know how it goes!
