Hello all,  
Problem when I send my audio stream from the TCP Sink to a media player.  
I have read the earlier mails and tried the examples with TCP  
Source/Sink in GRC.  
They look like this:  
(tcp\_sink\_test.grc): Signal Source --\> Throttle --\> TCPSink  
(tcp\_source\_test.grc): TCP Source–\> WX GUI Scope Sink  
And they work well.

Actually I would like to hear the Sound from a median player (like VLC  
media player). So I replace the Audio Sink from the “dial\_tone” example  
with the TCPSink(tcp://127.0.0.1:12345).  
Then I open the VLC media player and give this address to VLC.  
“tcp://127.0.0.1:12345 - VLC media player” is showed on the top of the  
VLC window and the WX GUI Slider is also showed, so that I can change  
the volume and the noise. But I cann’t hear anything from VLC…

But when I run this Flow Graph: File Source(with a wav file)–\>TCPSink  
This time I can hear the music that I imported in the File Source. So I  
suppose that my VLC player itself is not brocken.

Any idea why the still?

Thanks

Lu
