Pulseaudio network stream gets recurrung short interruptions

[Dirk Seidel]

I use pulseaudio to stream music over wifi to a Rasberry Pi 2 at 192kb. Exactly every 5 minutes there is a short dropout in the stream. This is always followed by the following warning in plamashell:
networkmanager-qt: void NetworkManager::AccessPointPrivate::propertiesChanged(const QVariantMap&) Unhandled property "LastSeen"
which comes from the corresponding function in accesspoint.cpp. See (line 211):
http://api.kde.org/frameworks-api/frameworks5-apidocs/networkmanager-qt/html/accesspoint_8cpp_source.html

I am running on Vivid with kubuntu-ppa-ubuntu-backports-vivid.

Status changed to 'Confirmed' because the bug affects multiple users.

Happening for me with the latest 5.4.3 in Wily.. off to hunt for an upstream bug.

I'm now on 16.04 and the problem still persists. It even got worse, as now, the short dropout happens exactly every 2 minutes.
