wine users - Jun 2009 - Dawn of War alert sounds not working

Hi, I'm using Ubuntu 8.10 with wine 1.1.22, and I've got a problem with
dawn of war original. When I load up a skirmish or multiplayer game, the sounds
that a unit or building make when clicked on do not play. In addition, the
sounds made when a unit is taking fire for example, don't play either. When
I reload the skirmish game again, everything works fine. I've got no idea
what's going on, I'm using pulseaudio, but when I was playing the dawn
of war demo and not using pulseaudio, the problem was there too.

Any idea? Any extra info needed?

I'm hoping someone out there has some suggestions. Also, I'm using OSS
in winecfg, and using the command aoss padsp wine W40k.exe as my command.
