Audio samples played through both servers, config files, and logs.

On a fresh install of raspbian lite (no X) running on a new Raspberry Pi 2B
(happened on an Pi 1B too, but data here is for 2B), the pulseaudio daemon
garbles data via the native TCP plugin. This issue has been happening to me
since version 6.x.

Repeat steps:
* Get Pi 2B (maybe other models too).
* Attach speakers and ethernet to the Pi.
* Install Raspbian lite.
* Install prerequisites for pulse (my configure log is in the attached
archive).
* make && sudo make install
* Add the following to /usr/local/etc/pulse/default.pa :
    load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;{your subnets
address}/24 auth-anonymous=1
    load-module module-zeroconf-publish
* Edit /usr/local/etc/pulse/daemon.conf to set:
    exit-idle-time = -1
* Run:
    export LD_LIBRARY_PATH=/usr/local/lib 
  Or set the variable for every pulseaudio call, or put the export in bashrc.
* As the 'pi' user, run:
    pulseaudio -vvvvvvvvvvv
(pulseaudio should start fine, speakers should hiss for a few seconds, then
fall quiet)
* Optionally test that loading the sine module produces a tone.
* On your computer (or the pi if you want), run:
    paplay --server={Pi's IP} {Some wav file, ideally a song}
(Assuming your network is fast enough the audio should start up, and play fine.
Listen to pa_test_good.mp3).
* Kill the pulse server.
* As the 'pi' user, run:
    sudo pulseaudio -vvvvvvvvvvv
(pulseaudio should start fine, speakers should hiss for a few seconds, then
fall quiet)
* Optionally test that loading the sine module produces a tone.
* On your computer (or the pi if you want), run:
    paplay --server={Pi's IP} {Some wav file, ideally a song}
(Everything is awful. Listen to pa_test_broke.mp3).
