  Are you trying to play a .wma file or a .mp3 ?? The command line below is for
mp3 decoding.

Several points:
.There are know issues with the ffmpeg mp3 decoder. You're better off using the
mad decoder (gst-plugins-bad) or the fluendo mp3 plugin
(http://store.fluendo.com).
.You should try using the following command line when decoding a file,
decodebin will take care of figuring out the correct elements to use:
gst-launch filesrc location=... ! decodebin ! alsasink
