I just encountered this same symptoms today in my newly upgraded ubuntu (from LTS 12.04 to LTS 14.04): 100-150kB upload to 224.0.0.56 and my wifi down to less than 1Mb effective bandwidth.
There were a few updates today which seem to have triggered the behaviour, as I had no problems before the update. But I cant seem to find the update history so I can't tell you which packages - it included a kernel update & reboot. I'm now running 3.13.0-24-generic. Disabling rtp-send as per #5 works around the problem - and I'm not planning on streaming any audio any time soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/411688 Title: pulseaudio floods network with multicast packets To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/411688/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
