Dear Maintainer,
I set up my home network to stream music to multiple rooms. Upon starting to play music I noted that it would randomly (within 5 songs/~30minutes) stop playing. In banshee the UI would be showing that the song immediately previous to the one it halted in was playing. Additionally, both banshee & rhytmbox did not move the sliders indicating where in the song the playback was. Other methods of playing music also exhibit problematic behavior. Google play's online player does't move the trackbar, stutters, then skips to the next song. Youtube shows the same trackbar not moving and does not display video, although sound plays. It would appear this is present no matter the audio source.
I unfortunately have little to go on for this bug. I have no experience debugging pulse and this behavior is too weird for me to even guess where to start. My debugging consted of isolating the problem to tunneling sound. In other words, after I observed the problem, I went back to using just my local speakers. All problematic behavior disappeared.

As a final note, mordor (referenced in the configuration file) is a gentoo server running pulseaudio 5.0-r4 (stable). As this is a sessionless server, it is running as a systemwide daemon.
mordor ~ # equery u pulseaudio
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for media-sound/pulseaudio-5.0-r4:
U I
+ + X : Build the X11 publish module to export PulseAudio
information through X11 protocol for clients to make use.
Don't enable this flag if you want to use a system wide
instance. If unsure, enable this flag.
+ + alsa : Add support for media-libs/alsa-lib (Advanced Linux Sound
Architecture)
+ + asyncns : Use libasyncns for asynchronous name resolution.
- - avahi : Add avahi/Zeroconf support
- - bluetooth : Enable Bluetooth Support
+ + caps : Use Linux capabilities library to control privilege
+ + dbus : Enable dbus support for anything that needs it (gpsd,
gnomemeeting, etc)
- - doc : Build the doxygen-described API documentation.
- - equalizer : Enable the equalizer module (requires sci-libs/fftw).
+ + gdbm : Use sys-libs/gdbm to store PulseAudio databases.
Recommended for desktop usage. This flag causes the whole
package to be licensed under GPL-2 or later.
+ + glib : Add support to dev-libs/glib-based mainloop for the
libpulse client library, to allow using libpulse on
glib-based programs.
- - gnome : Use GConf to store user preferences on streams and so on.
Don't enable this flag if you want to use a system wide
instance. If unsure, enable this flag.
- - gtk : Add support for x11-libs/gtk+ (The GIMP Toolkit)
+ + ipv6 : Add support for IP version 6
- - jack : Add support for the JACK Audio Connection Kit
- - libsamplerate : Build with support for converting sample rates using
libsamplerate
- - lirc : Add support for lirc (Linux's Infra-Red Remote Control)
+ + orc : Use dev-lang/orc for just-in-time optimization of array
operations
- - qt4 : Add support for the Qt GUI/Application Toolkit version 4.x
- - realtime : (Restricted to >=media-sound/pulseaudio-0.9.21.2-r1)
Makes PulseAudio use RealtimeKit (sys-auth/rtkit) to get
real-time priority while running.
+ + ssl : Use dev-libs/openssl to provide support for RAOP (AirPort)
streaming.
+ + system-wide : (Restricted to >=media-sound/pulseaudio-0.9.21.1)
Allow preparation and installation of the system-wide init
script for PulseAudio. Since this support is only
supported for embedded situations, do not enable without
reading the upstream instructions at
http://pulseaudio.org/wiki/WhatIsWrongWithSystemMode .
- - systemd : Build with sys-apps/systemd support to replace standalone
ConsoleKit.
+ + tcpd : Add support for TCP wrappers
- - test : Workaround to pull in packages needed to run with
FEATURES=test. Portage-2.1.2 handles this internally, so
don't set it in make.conf/package.use anymore
+ + udev : Enable virtual/udev integration (device discovery, power
and storage device support, etc)
+ + webrtc-aec : Uses the webrtc.org AudioProcessing library for enhancing
VoIP calls greatly in applications that support it by
performing acoustic echo cancellation, analog gain
control, noise suppression and other processing.
- - xen : Builds a special paravirtualized module for running in a
Xen guest.
