Are you streaming files or line-in?

Yesterday I experienced something that sounds quite a lot like what you
are experiencing now. 

I was streaming from line-in and noticed I had forgotten to mute
the line-in playback. The line-in playback got outputted to the mixer
again, which in turn went straight back into line-in causing a
nifty loop with a nasty "tin can"-effect and echo.

Make sure you've muted everything you don't need on your
streamsource machine and use the latest stable versions of Lame and
