perfect sound in KdeTV but not in VLC

Hi there!

I am really desperate and hope somebody here can help me. I have the 
folllowing problem:
KdeTV works perfectly. I start it and get video+sound without any 
problems. But my aim is to use VLC to stream the video+sound data over 
ethernet. So I start VLC and it can capture the video no problem there, 
BUT it doesn't get any sound!
I already checked the /etc/asound.state (stored it while kdetv running 
and stored it while kdetv not running and compared it) but there are no 
differences when kdetv running or not, so it doesn't mess with my mixer 
settings.
The really strange thing is that kdetv somehow switches the audio on and 
switches it back to off when I close it (mute on exit is deactivated).
When I first start kdetv and then vlc, vlc is able to capture the sound, 
but thats not a real solution.

I really have no idea what to try next.

Thanks in advance
