Pitch alterations not working in an Android build

I’m working on a game right now and at one point I have some dynamic music playing, getting progressively faster as level goes on. I achieve this through simple pitch += 0.05 at set intervals in my blueprint and it all works great - on PC. As soon as I package the game and run it on my phone, though, that sound never changes pitch at all, it just stays constant at pitch == 1 (the default) and does not react to the proceedings on the screen. Why is that so? Is dynamically changing pitch at runtime blocked on Android and I have to somehow explicitly force it in my build settings?

No way to make it work? :frowning:
