If you're experience bad sound with the default WINE package in Ubuntu and have Pulseaudio working, you should try the following WINE package (available in an Ubuntu PPA) which comes with built-in Pulseaudio support.
I couldn't get PulseAudio to work on one of my computers no matter what I do. But removing PulseAudio can be tricky and besides, there is a very easy way to "fix" it (if you're using GStreamer as a backend for music and videos).

Ubuntu or PulseAudio actually really needs a good system wide equalizer. A project which initially begun as a simple script (actually it still is a script) now has become a fully working system wide PulseAudio equalizer. In the recent version, thanks to psyke83 the script comes with:
