Slowed audio playback in android phone unity 5

I recently updated my Unity to 5.2.2
In my game I have just one gameObject with AudioSource attached.
In this AudioSource I have Loop and Play on Awake set.
This worked fine on my i9300 (android 4.4.4) but after update my sound is playing very slow.
In the editor everything works fine, but after installing app on phone, music don’t work properly.

I have tested this on other android phone (android 4.1.2) and everything work good.

In links below there is sample

correct music: Dropbox - Error - Simplify your life

slow music: Dropbox - Error - Simplify your life

Anyone got any idea how to solve this?
Thanks in advance

But even with that fix my sounds are not as clean as they were on old unity version :confused:
