gst-launch-0.9 sinesrc ! osssink works, but gst-launch-0.9 sinesrc !
audioconvert ! osssink doesn't (see error above). But its not that simple, with
gst-launch-0.9 sinesrc ! audiorate ! audioconvert ! osssink I get a nice clear tone.

This last trick doesn't work for bigger pipelines:

===================
gst-launch-0.9 filesrc location= AniMix_Project-Full.512x384.XviD.avi ! avidemux
name=d d. ! queue ! mad ! osssink d. ! queue ! ffdec_mpeg4 ! ffmpegcolorspace !
xvimagesink
===================

Which will play happily to the end of the avi, but when I put audioconvert in
between mad and osssink it bugs out with the error in post #0 above.
If I put in audiorate ! audioconvert between mad and osssink I get this:
Note: I don't know it audiorate ! audioconvert is allowed, but because it worked
with sinesrc I tried it here too.

===================
PAUSE pipeline ...

(process:10870): GStreamer-WARNING **: timeout in PREROLL, forcing next state change
PREROLLED pipeline ...
