Bug Description

Sound in HTML5 games works fine with pure alsa, but it has problems with pulseaudio.

http://darkphear.elementfx.com/webgames/test1/ (Press ENTER or Z to shoot)

1) In firefox the sound effect sometimes plays at the right timing, sometimes it plays half a second later, sometimes it doesn't play at all.

2) In google-chrome the sound effect always plays at the right timing, but it seems to cut before the sample finishes.

Well, it's factory settings because I didn' t change it.
How to reduce the latency then?
