Hi all!
My first post here, I'm an occasional pd user, and I was fiddling with PdDroidParty, a nice app to run pd patches on android devices.

I installed it and tried an example patch, it works! So I know that it is compatible and everything, controls respond and sound comes out.

Then I tried to create my own patch, but I can't really get it to work and I don't know why, I even made a super-simple beep patch, you can download it here, and still nothing, I can see and use my GUI on my phone, but no sound is coming out, I really don't know what to do at this point, can you find the error?
Thaaaaanks!
