This might actually explain the issue!

@Bruno: what is you current value of "Delay" in the audio settings and 
what is your Jack buffer size?

Actually, before Pd 0.52, the polling scheduler did not really work 
correctly together with the Jack backend, i.e. the "Delay" setting was 
basically ignored and it just did double buffering. This has been fixed.

Anyway, Pd should make sure that "Delay" is not smaller than the Jack 
buffer size, thus preventing silent output. If that's not the case, 
please file a bug report!
