I can play mp3 files without any problem, also in my application playing PCM data from appsrc is working well, however I have a problem playing a WAV file using the gstreamer command:

$ gst-launch-0.10 filesrc location=sound.wav ! wavparse ! audioconvert ! alsasink

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

Have you already installed gstreamer goog plugins?

apt-get install gstreamer0.10-plugins-good

Then try to convert WAV:

gst-launch-0.10 filesrc location=path_of_input_wav_file ! wavparse ! filesink location=path_of_output_file

Yes. I have it already installed. Your command is working fine (I got some result file). So it looks like wavparse plugins is OK. audioconvert plugin is also fine as command filesrc location=Sound.mp3 ! mad ! audioconvert ! alsasink is playing fine. –  kappa May 21 '12 at 4:44
