tv streaming sound problem

[bArde]

Hi everyone,

I want to stream TV from my TV card (on a FC3 server) to winXP and linux clients, with vlc.
The video streaming works well.
But I have no sound. I really don't understand why because it seems I have no error on the server's log.

the command line is :
vlc -vvv --color --sout '#transcode{vcodec=mp4v,vb=4000,venc=ffmpeg{keyint=80,hurry-up,vt=800000},scale=1,acodec=mpga,ab=128,samplerate=44100}:std{access=udp,mux=ts,pcr=100,url=239.255.1.1,sap,name="F2"}' v4l:/dev/video0:size=640x380:frequency=623250:norm=secam:adev=/dev/dsp:audio=0

the server's log first lines are :

I'm lost and don't know what to do.

Anyone has already have the same pb ? Any Ideas ?
thanks
