Thank you very much.
You are right: if I'm using MPlayer the sound is working.
The reality is that I'm using XBMC for playing all video files and live streams (XBMC is using librtmp.dll for live streaming) . The player that XBMC is using is dvdplayer, and seems that the sound is not working with this player
.
Do you have any suggestion to make the stream working in XBMC?
