I had the same issue (no sound, or only a couple of seconds of crackly sound after killing pulseaudio) and was able to fix it with Wine 1.4.1 installed by running:
$ export WINEPREFIX=~/.limbo/limbo
$ winecfg
Then under the "Audio" tab, manually selecting and output device instead of leaving it at "(System default)". For instance, for my sound card I selected "HDA Intel - ALC663 Analog".
Limbo now runs fine with sound when run using the installed shortcut.
