problem with loudspeaker

[gulux]

Hi everyone ! First of all, excuse me for my language, I'm a french and I don't speak english very well.
So, my problem is that I can't watch any video (on YouTube or on the internet), I can't listen musics with the loudspeaker. It work perfectly with the headphones. But, when I have a sms or phone call or notification (Facebook, Twitter, even the alarm), the loudspeaker work. I rebooted my phone several times, it's still not working. I hope someone can give me a solution, I use this phone since 2 or 3 weeks. Thank you everyone, good bye 😉

Do you root or flash the phone before the problem happens? If yes, do it again.

Try to safe model to check if it caused by the 3rd APP you have installed.
