Very quiet notification sounds on 5.0.2

Hi, I noticed that on my d802 5.0.2 lollipop notification sounds are very quiet. If I choose one of the notification sounds from Zedge and I set it to notification sounds it gets more quiet than in the app. I can't hear any incoming SMS when my phone is in my pocket. Is there any fix for this ? The way without root would be the best.

XT1096 Speaker volume quiet at start

I have a strange problem with my Moto X XT1096. At full volume, the phone rings as if I have turned on the 'Increasing ring' option although I haven't turned on any such feature. Because of this, the phone starts ringing at low volume which eventually gets loud after 2 seconds.

Is this normal? By the way I am using official 5.1 update.
