Sorry to say this, fenris, but sound has never been an issue, it just worked after creating both Ubuntu 13.04 and 13.10 beta guests in VMware Fusion 6!I'm sure you've already checked this, but do you have the sound device switched on in the VM settings file? The Ubuntu guest claims to have a Creative Sound Blaster AudioPC164V, AudioPCI128 card installed if I look in System Settings -> Sound. This site may be helpful:
