            Status: UNCONFIRMED

Please describe the problem:
ela:~$ LANG=C gst-launch audiotestsrc wave=1 ! alsasink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: audioclock0

Works fine. If i select the default device explicit:

ela:~$ LANG=C gst-launch audiotestsrc wave=1 ! alsasink device=hw:0,0
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /pipeline0/audiotestsrc0: Could not negotiate format
Additional debug info:
gstbasesrc.c(1717): gst_base_src_start (): /pipeline0/audiotestsrc0:
Check your filtered caps, if any
Setting pipeline to NULL ...
FREEING pipeline ...

Does not :(  So i expand the pipeline to

ela:~$ LANG=C gst-launch audiotestsrc wave=1 ! audioconvert ! audiorate !
alsasink device=hw:0,0
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: audioclock0

which works fine again, but if i now change to the spdif output (hw:0,4)

ela:~$ LANG=C gst-launch audiotestsrc wave=1 ! audioconvert ! audiorate !
alsasink device=hw:0,4
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /pipeline0/alsasink0: Could not get/set settings from/on
resource.
Additional debug info:
gstalsasink.c(604): set_hwparams (): /pipeline0/alsasink0:
Rate doesn't match (requested 44100Hz, get 0Hz)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
FREEING pipeline ...

A simple 

gst-launch sinesrc ! alsasink device=hw:0,4 works on this computer with gst-0.8
