I have the same problem as the original poster and I'm willing to provide any necessary debugging information. This bug has been here for several Ubuntu releases (currently running 9.04). I work around the problem by clicking "Click here to listen with your default audio player" and then right-clicking and opening the file in "Movie Player".
Here is the output from running "gst-launch" (no audio):
$ gst-launch-0.10 playbin http://cougar.eb.com/soundc11/c/crysta02.wav
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPlayBin:playbin0: No URI specified to play from.
Additional debug info:
gstplaybasebin.c(1642): gen_source_element (): /GstPlayBin:playbin0
Setting pipeline to NULL ...

Sound preferences are mostly "autodetect" with sound capture=>ALSA and device=>Intel ICH6 (Alsa mixer)
I don't know how to tell what sound card I have but it is probably the generic AC97.
