Hi all, me again  
The sound library is working fine on the pi, but I am getting an issue (and I noticed someone on GitHub having a similar recent issue, but as of now that thread is unresolved)  
I am trying a super simple play back sketch but when I try to load a three minutes long uncompressed wave file I get an  
ArrayIndexOutOfBondsException: 3 Message from the Processing compiler. I am guessing it is more of a java issue, but I don’t know how to fix it. Is there a maximum file size for Audio on the Pi ? (I am guessing not since I am using a 16GB simcard for storage) Any ideas what this problem could be?  
Many thanks

@gwenn That’s with the latest Processing Sound library?

@gwenn I see - this is then probably the same as [Issue #14](https://github.com/processing/processing-sound/issues/14). You might want to post one of the files that doesn’t work for you there.

This this gets fixed, you could try using the [old sound library](https://github.com/processing/processing-sound-archive/releases). Its latest (last) release does support ARM platforms, such as the Raspberry Pi.

Edit: alternatively, you could also try using the _Minim_ library.

Hi Gotfried. Thanks for responding. In the end I chose to use Minim because I am already familiar with it. And now everything works. I still get weird messages in the P5 compiler window but I think it has more to do with Java and the code used in the playback example. In any event sound plays and it sounds good.

To reiterate I am playing back audio on the pi 0. I used Adafruit example to reassign some of the pins. YOU can play audio out of the pi 0 (without spending money on a usb gadget). Let it be known 🙂
