Good, first to excuse me by my English since it is not my language.

What I want to do is to reproduce a sound in my map (in all the map) but every certain established time, for example every 30 seconds.

I wait for your answer and thanks for everything.

A greeting

make a 30-second loop with the sound at the begining or the end, and dead space to fill the rest??

or you could use a looping multi_manager
