On latest Hardy amd64 running on Lenovo N100 laptop with Intel HDA sound card sound does work through PulseAudio, but programs relying on ALSA don't work properly.
For example, aplay always reports that alsa device is busy. VLC doesn't produce any sound. So does Twinkle as well.
Creating /etc/asound.conf as suggested in https://wiki.ubuntu.com/PulseAudio (this file is not created by default) doesn't help too much. In this case, aplay works as intended. VLC produces sound, too, but on attempt to stop playing PulseAudio hangs completely. Skype doesn't produce any sound. Twinkle produces no sound output, though microphone works correctly.
