LG G2 D802 /e/OS 1.8.1 sound problem

In volume settings, the only sound that works on the speakerphone is Call Volume. The others only work via the Jack socket or via Bluetooth. In fact, no multimedia sound is audible through the speakers. You need wired or Bluetooth headsets to hear them.
The ringer only works in vibrate mode.
From what I remember, everything worked normally when this phone was under Lineage.
Thanks in advance if you have any Idea.
