pulse driver fails to play short samples

[GoogleCodeExporter]

This is Fedora 17 with pulseaudio 1.1 and pyglet from the repository (1.2 
alpha1 +) and avbin 11 (alpha4 I think, although I think it's unrelated).

Pulse driver doesn't play short samples properly, for example:

$ sox --info sample.wav 

Input File     : 'sample.wav'
Channels       : 1
Sample Rate    : 22050
Precision      : 8-bit
Duration       : 00:00:00.13 = 2850 samples ~ 9.69388 CDDA sectors
File Size      : 2.91k
Bit Rate       : 180k
Sample Encoding: 8-bit Unsigned Integer PCM

This wav file is played properly with openal driver.

I'm attaching a wav sample and a test.py.

Still happening with pulseaudio 3.0.

I get the following error when trying to play the sample:

Can you try AVBin 11 alpha4? https://github.com/AVbin/AVbin/downloads
