Pitch slow p9 lite

[spinus1]

In my p9 lite downloaded music is played with a slow pitch, the difference is minimal, but if you pay attention you can notice it.
It does not happen with stream songs.
I have no equalizer in the system and I have disabled automatic gain control...

Hey @spinus1, welcome to the Spotify Community! 

Do you have more than 1 device available for offline use? If so, do you hear the same pitch if you try to play a song in the Offline Mode from that other device?

Also, let us know the Spotify version you're running. 

Keep us posted.

I'm using version 7.5.0.1076, other devices are working fine.
I'm not sure but this could be related to the fact that when I was experiencing the issue the phone was short of battery, less the 8%...Maybe something related to battery save?
