When trying to run the attached code, sound is only output for a second,
and then disappears. If I restart the sketch, the sound is back, but again,
only for a second.

I have tried this code on different machines, on different OS, and all with
the same result.
I've also tried it with bot earlier versions of processing, and minim, and
today again with the latest version.
