Hi, Marco
   Thanks for your help!

   I have a question about this "gst-launch" command.
   How dose this command line routing sound stream to imx-hdmi-soc with alsasink?

BR,

In which format is the audio in this *.wav file? It's quite possible 
that it is not supported by imx-hdmi-soc, in which case you can try with 
gstreamer using audioconvert (gst-launch filesrc location=Noise.wav ! 
/wavparse/ ! audioconvert ! /alsasink).
 
Kind regards
