Considering this bug is over two years old and pulseaudio probably runs on 99% of all Linux desktops on the planet I'm a bit confused as to how this can be such a non-issue. Anyways, I can disable IPv6 on avahi as a workaround, although to me it looks like that bug should be trivially fixable by simply adding a v4/v6 suffix to the sink name. Also the tunnel module shouldn't fail entirely just because a duplicate sink name is requested. Instead I should be notified of the conflict by a log message on the ERROR level.
