Audio buttons suddenly not working

[QtzIbz]

Hello,

I have this PDF file that plays some audios with buttons, it runs with the 3D application I think.

I have a lot of this files which I use to study and suddenly they don't work. I have tried in other PC's and they also don't work anymore. Is this due to an update from Adobe?

What could be happening?
