Hm, maybe should give in to the addication and start playing the game 24/7 :D
When I tried it (for some 20 minutes or so) I did not notice any late
sounds with gstreamer. It might however also be that either the
gstreamer lib itself is at fault or our current git version contains
improvement for that, though I could not imagine what change could
have had influence on that sort of thing.

Yes that would be xine then, I also noticed missing foot steps with
xine, though I believe this to be a problem with the xine library. But
as the xine backend is a bit unmaintained (xine upstream actually does
not spit activity either) I am not sure we can get things moving
there. For testing I would very much recommend phonon-gstreamer
(ultimately with/from Phonn 4.4.3 or even git) or phonon-vlc.
By the way, you can check the backend in use via systemsettings'
multimedia category, which by default should show the Phonon KCM with
a  'backend' tab.

Well, very short sounds usually are even smaller in wav than they
would be in OGG-Vorbis in my experience so that makes perfect sense :)
What worries me though is that there are general problems with
inaudibility... I'll try to look into this for Phonon 4.4.4 (schedule
sometime soonish). Do you have any idea what other games are affected
by this?

Well, it would be awesome if you could test with latest git version of
phonon and phonon-gstreamer
