I think I just saw this issue also. I was seeing a lot of traffic over my wireless NIC going directly to one of three Apple AirTunes devices on my work network (the one I had connected to previously). Even though I set "Internal Audio Analog Stereo" under Sound Preferences/Output tab - so the AirPort was not selected, PulseAudio still was going nuts with traffic to it.
Before I had a chance to look into it further, another sysadmin had password-protected the device (apparently others were complaining that they could no longer connect to it to play music and rebooting the AirPort multiple times wasn't helping) and I could immediately see the outgoing traffic on the laptop stopped. I was so excited that I could finally play audio to these horrible proprietary devices (purchasing them wasn't my decision), but now it's password-protected I'm not sure PulseAudio can play to the device any more - even though I know what the device password is. I should point out that the laptop in question was actually running Debian testing, so this likely needs to be dealt with upstream by the PA guys. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
