Been googleing around for a few days now on that problem, nothing seems to work.
The sound coming out of the speakers is very, VERY low. It does so since I updated to Windows 10 and then resetted to factory status via windows 10. So low that you can hear it only if there's no other sounds and really concentrate on hearing it. I tested, and it's not white audio, it's really the right sound.
I blame this on realtek HD sound (the basic Windows sound driver).
Here's what I tried.
- Plugged my phone in my speakers, played music, came out of the speakers normally (with good sound.)
- Plugged headphones instead in the jack instead of the speakers, no sound in the headphones too.
- Front jack works fine.
So I know the problem comes from the back jack port, and not my audio setup.
EDIT: Also tried to update the drivers.
