MV : export, bug music with PC

[Laurent]

Hello, I have a problem with game export.
With a team, we created a game, and when I play on the game with my Mac, no problems. But some of my friends get some trubles with PC: music delay, it's a disaster!
I put a plugin to preload musics, but if I put this plugin, they can't play to the game. There is some freeze. 

I don't know from where comes this problem: they can play to the Witcher III without problems, but impossible to play a project by RPG Maker.

Why?
Thanks for your help.

we need more info before we can help - it can be anything from wrong audio formats (Mac and Windows have different codec defaults as far as I know), problems with background functions, simply a problem with browser access or the way the game is structured.

The music are in ogg. I converted more of them with this website: http://www.onlinevideoconverter.com/fr/mp3-converter
About PC: it's strange because a friend doesn't have any problems with his PC, but another friend yes. It's like 50/50. But why? Impossible to find if the problem comes from the game, or from the software.


What is the background functions please?
