Volume on S6 edge

[log6993]

What's the matter with the volume when I use Spotify on my galaxy S6 edge?! When I listen to music the volume increases and decreases on it's own... That's really annoying 😞 does someone have this problem too? Anything to do to fix that?
For your info, I already cleared all data (user and cache) several times. Resynchronized all my playlists (yes I'm premium) three times. Uninstall and reinstalled the app once. None of these things have fixed my matter... Please help me! Spotify ?

From what I can gather, it's a problem with SoundAlive. Disable that and it will solve your problem. I've got the same issue but don't want to disable it cause I think it sounds pretty good.

To disable: Settings>Sounds and Notifications>Sound quality and effects>Uncheck SoundAlive+
