Comment 5 for bug 411688

If I use padevchooser to specifically choose the internal audio as both default sink and default source, the network traffic is reduces somewhat but not by a lot (about 10%~20%).

I can cause pulseaudio to stop flooding the network completely by disabling the rtp-send module using gconf. I'll keep it disabled for now (as I do not have a real need at the moment for audio over the network) unless you want me to debug something.
