Low sound volume with headphones

Question

I have a dual boot ubuntu 18.04/windows 10 on my PC. On windows 10 the sound works fine whether it's coming from my headphones or the speaker of the laptop. In ubuntu, the sound is fine when it's coming from the speaker of the laptop, but very low when it's coming from the headphones. Any idea on why this could happend and how to fix it?

Answer 1

After some research, I launched alsamixer, and there my Headphone was at 100 and my Speaker at 0, I put the Speaker at 100, and my volume is now at a normal volume in my Headphones.
