To me it looks like your programs exit before they can play the sound. Try using
import gtk; gtk.main()
at the end of your gstreamer code. This will enter the GTK mainloop, and thus also the glib mainloop which is used by gstreamer.

Thanks a lot, but running
Gets this:
Any ideas...?
import pygst
pygst.require('0.10')
import gst
import gobject, sys
def play_uri(uri):
" play an uri like tada.wav "
player = gst.element_factory_make("playbin", "player")
print 'Playing:', uri
player.set_property('uri', uri)
player.set_state(gst.STATE_PLAYING)
play_uri("/home/user/tada.wav")
import gtk; gtk.main()
Nokia-770-36:/home/user# python sound.py
Playing: /home/user/tada.wav
python[2166]: GLIB CRITICAL ** GStreamer - gst_element_make_from_uri: assertion `gst_uri_is_valid (uri)' failed
python[2166]: GLIB CRITICAL ** GStreamer - gst_uri_get_protocol: assertion `gst_uri_is_valid (uri)' failed

Update:
The error messages stopped when I added the file:// prefix before the uri, ie:
But still no sound...

Aisu:
I am just a learner myself, but I have dabbled with sound in pygame just as you tried. I reduced my (working) program to a bare minimum, and for me on my desktop python (not yet confirmed in maemo python) it works fine for me as long as the python program itself runs long enough to actually *play* the sound file. To artificially make your program do the same, try adding this final line to your python file:
pygame.time.delay(5000)
For my actual program, it doesn't need this because it is a non-serial program that constantly polls the keys being pressed -- if you know what I mean.

Thank you, thank you, thank you! Perfect! It works! Now I just have to find the right sounds 
I haven't been able to find anything that works to simply play a wav on maemo, I've tried...
But nothing seems to work... could someone please just show me a snippet on how to play a wav on the tablets? Thats it, no need to stop or pause or anything else, just play it. It would be greatly appreciated!
Thanks.
