This doesn't affect the result of the testcase. count is only used to pause and resume less frequently than every iteration of the write loop.
I can confirm that the program seem hang after a few pause/unpause when using alsa-pulse plugin
However it assert when using hw device
assert(bsize / psize >= 4);
The assert is present because I've only tested on systems where this assertion holds true. It's likely that the loop timing would need to be changed to work correctly in other cases.
Thanks for confirming that you can reproduce the problem. I've since discovered that it's possible to produce the same problem with the PulseAudio API directly, so I'll take this up on pulseaudio-discuss@.
