Asunto: [Bug 411688] Re: pulseaudio floods network with multicast packets

killall pulseaudio didn't fix it, but:

# chmod 0600 /usr/lib/pulse-10.0/modules/module-rtp-send.so

followed by killall pulseaudio again did and this will doubtless work until the package is updated.
I have no idea why this issue popped up today. I haven't made any changes to my sound settings for a while and the timestamp on ~/.gconf/system/pulseaudio/modules/rtp-send is July 2012.

Bug description:
  Binary package hint: pulseaudio

  Since a karmic update last week, when pulseaudio is running it floods
  the network with multicast packets, to the point where the wireless
  interface I'm using is so flooded that no other network traffic can be
  transfered.

  Here is a snippet of tcpdump -i wlan 0 -n:

  As can be seen, these packets are sent several hundreds times a second
  and this completely overloads the network interface.

  Apparently I have pulseaudio set with network access enabled, but I
  can't disable it as the pulseaudio configuration is completely
  disabled (see screenshot).

  As pulseaudio keeps recovering itself the only way I can get any work
  done at the moment is to run "while true; do killall pulseaudio; sleep
  1; done" whenever I want to do anything on the network.
