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 ...
ERROR: from element /GstPipeline:pipeline0/GstWavParse:wavparse0: Internal data flow error.
Additional debug info:
gstwavparse.c(2046): gst_wavparse_loop (): /GstPipeline:pipeline0/GstWavParse:wavparse0:
streaming task paused, reason not-linked (-1)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...

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
