I have all I think.. but what I don't understand is that I can use the MPGA
or A52 codec to stream out, and I could listen to it on a Windows client,
but I can't listen to that sound on Linux using the same codec... :O(

Could the problem come from the audio drivers ?

The problem is always :
"main audio output error: couldn't find a filter for the conversion"
