The fact that the shell is hanging suggests to me that either the
audio pipeline thinks it is working correctly; or, it tried connecting
to pulseaudio and is in a wait-forever loop trying to successfully
connect.
But typically you won't hit the "PLAYING" state and the
"GstPulseSinkClock" won't be created, if there is a connectivity issue
to the pulseaudio daemon.
Sounds like you might actually have a working pulseaudio daemon, but
the volume is muted ;) Can you look in the pulseaudio sound control
app you use (I'm not sure what it's called or if one exists for Sugar)
? If you want, install the pavucontrol package -- that should work
reasonably well for this purpose on F14. It will show up in menus as
"Volume Control" or "PulseAudio Volume Control" or it can be started
from a terminal with
pavucontrol #do not run it as root
Then look through the volumes and make sure that
(1) the gst-launch *stream* is not muted, and
(2) the hardware sound card *sink* is not muted, and
(3) volume is turned up sufficiently on both the sink and the stream
I don't fully understand everything in your PA log file below (and
certainly there are a few scary messages there), but it looks like PA
successfully started up in the end, so the only other thought I had is
that maybe your ALSA driver is hanging when trying to play audio
through pulseaudio, and that may very well be solved by a distro
upgrade to F16 or F17 (F17 was released as final / production this
week).
