Hi all.

I am not sure, if you are facing the same problem which bugged me a week
back (though I am unsure if this is a problem, or a feature), but here it
goes like this ::

I noted that for the very first time, the pulseaudio sink volume is muted.
So, I noted that when I did something like
                      "gst-launch filesrc location=/path/to/mp3" ! mad !
I could hear the sound.

However, when I did
                      "gst-launch filesrc location=/path/to/mp3 ! mad !
I could not hear the sound.

So, I launched "pavucontrol", unmuted the sound in "Output Devices"
section, and volia . I could hear sounds from thereon using "pulsesink"
(and "alsasink:, of course).

Is this the same case as yours..?
