iOS: Changing volume while audio is playing breaks/pauses audio

[IbrahimYildirim]

Which API doesn't behave as documented, and how does it misbehave?
iOS When calling setVolume() with value from a Slider the playing audio pauses/breaks and continues only after the slider thumb has been released

Additional context
This started to happen recently on my affirmation app where users record affirmations with their own voice and have it played in loop with a short break in between. This used to be smooth but now it's lagging when changing volume

After deeper digging I realise this issue only happens when the same audio file from assets is used multiple times in the playlist.
When removing the assets audio in between it works smooth.

@IbrahimYildirim could you please explain more? what changes required at code level?

@richanshah by commenting out line 16 on SimpleAffirmationPlayer on my example.

Basically this issue only persist of there is a lot of the same audio file from in the same playlist. So when removing the silent audio from my assets folder that I am using as break in between the tracks, it works fine.
