Why doesn't it immediately play vk audio recordings?

Question

Hello,
I noticed such a thing that audio recordings, when turned on, do not always start playing right away, to play, you need to click on the play, and then, as it were, rewind it to the beginning.
This error is observed after I turn on the second track and beyond. If the tracks themselves play one after the other, then everything is fine.
flash player latest version.
What could be the problem?
Thank you very much in advance!
