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:

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

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