There isn't a consistent howto out there, so here's how to get pulseaudio support for wine in opensuse 11.4

You will first need to remove the installed versions, remove wine gecko first followed by wine 32 bit and finally wine. This prevents dependency resolution issues.

Now acquire some pre-compiled RPMs that support wine-pulse.

Thank you serkbugs2

Now, acquire the needed RPMs and install with rpm -i .

You will most likely need to delete your current .wine directory; it will attempt to update it, but will likely fail.

All you have to do now is run winecfg and select PulseAudio as the audio driver.

NOTE: A test sound will not play, so test it with a real application.
Good luck.
