I now have a rooted version with the altered mixer_paths.xml, but to answer your questions, the top speaker next to the led indicators is so quiet only during making a call, volume was at max and the voice enhancement made no difference. Not sure in safe mode and in that mode can you make/receive calls. But as i have said earlier i fixed it by replacing the standard mixer_paths.xml with no other alterations but rooted.

Hello
I suffer from a decrease in the volume?
What is the solution?
Hi tah12, welcome to the community!
Could you please clarify when exactly you experience low volume? So that we can troubleshoot accordingly for you 
I am using Xperia Z3 with Lollipop 5.0.2, I have experienced that ringing volume automatically decreases many times even I always set it in maximum range. Does anyone have the same problem with me? Please tell me how I can fix it? Thank you
