Loop Sound while Button is pressed

Is this possible with bb2?

If not, are there work arounds? Thanks.

 

I am also having same issue.
For example, sound is looping when user holding to duck in "The Pit" game.
But if you put a sound on advanced move, it only runs one time.

Any idea appreciated?

 

Same here.

Is there any way to add loop sound in World UI?

I tried to use Action button and added click sound, but it played once.
