Hi guys,

I’m trying to play this mp3 file but I keep getting this error message:  
Could not run the sketch (Target VM failed to initialize). For more information, read revisions.txt and Help ? Troubleshooting  
I updated my nvidia drivers as there was no option to rollback. Anyone know how to fix this?  
Thanks.

</div>

in your code possibly the last 2 } } are missing?

the last lines,  
4 lines about sound,  
you read ( load song from data/ ) and start a sound.  
but that is inside DRAW and inside a FOR 13

so you actually try to read and start that song 780 times per second.  
( what i think is that none of the 4 lines should be inside DRAW )

> as this question is about play a sound only, pls  
> play first in a extra little “project” to get that running.

and for your sinus i hope what i answered  
[Need Help Animating This Drawing](https://discourse.processing.org/t/need-help-animating-this-drawing/9446) ,  
can help.

Also, even more importantly, the lines

> [@Mahubis](#):
>
> import processing.sound.\*;  
> SoundFile file;

should come at the _very_ beginning of the file, even before the setup() method!
