Bug Description

Pulseaudio network sinks used to work couple of Ubuntu releases ago. Now they are broken in precise and i decided to figure out why. This is the reason:
https://bugs.freedesktop.org/show_bug.cgi?id=40785

Disabling ipv6 in avahi config works as a workaround, but this seems to be a bug in pulseaudio. Ipv6 is enabled by default.

   one of the best features of pulseaudio is broken on account of this bug.

This seems to be fixed upstream, but still fails with current pa version in ubuntu 14.04 (4.0-0ubuntu11).
