audioproblem

Multiple Audio Source is turned on but when I receive a notification the volume of the music being played suddenly decrease and rise again after. It's quite annoying when you're listening to music.

hi guys! Here my problem: my telegram audios recorded from telegram with headphones (with jack 3.5) are heard very low. I tried different headphones (iphones too) but nothing. On the other hand, with headphones without cables and without headphones, it feels very good.... Any advice? Screnshot...
