I realized I did not start banshee as recommended (and I have not uploaded the 2nd log).
I upgraded pulseaudio from ppa:diwic/fighting-rewinds, then I performed the test again, this time following the instructions.
During the test, the sound was indeed broken as expected, with long pauses between short fragments correctly played.

I attach both logs.
