Did you load module module-http-protocol-tcp as well as
module-rygel-media-server in pulseaudio? This error and the 0 bytes
indicate that the actual stream source is missing.

Also, in Ubuntu, the monitor sources tend to be muted by default, you
need to unmute it using pacmd set-source-mute (That's for later if you
get a stream but no audio output).

It should "just work" when module-http-protocol-tcp is loaded.
Unfortunately module-rygel-media-server does not do this automatically.
