[gst-devel] problem with alsasink

[Mathieu]

Hi,

i'm trying to use gstreamer with alsasink, but i got these errors when i try
to pipe through alsasink :

:: gst-launch filesrc location="file.mp3" ! mad ! "alsasink"

i am using gstreamer 0.6.3 with alsa drivers 0.9.6

is there a new syntax to specify the device to use ?
is alsasink supposed to work ?


thanks in advance,
