Yes, you are right, thanks for the correction. I was recording with this 
command-line. I tried the following, and got the same error as with 
gstreamer-properties. Would you have any idea?

gst-launch-0.10 filesrc location=my.ogg ! oggdemux ! vorbisdec ! 
audioconvert ! audioresample ! alsasink device=hw:1
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(570): 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 ...

Thanks,
Rodrigo
