Hi,

I'm Trying a simple pipeline which is not working :

arif at dev:~/GS_samples/sample_media$gst-launch-0.10 filesrc
location="M1F1-Alaw-AFsp.wav" ! alawdec ! autoaudiosink
--gst-debug-level=2
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

What i'm doing wrong? I want to understand it conceptually.
