I´m working on a sketch where I´m using an Arduino for an interface and want to trigger some sounds with it.

My problem relies on when I trigger the sound before I start the arduino port, in the 'void setup' it works fine, but when I try to trigger the sound after I start the arduino port, like in 'void draw', it won´t make any sound.

Is there any incompatibility when using these two libraries together?

Thanks!
