That is a slightly different use-case. You can kind-of simulate it with
gupnp-av-cp from gupnp-tools by setting the renderer to your device and
browse rygel.

Can you provide:
 a) the version of rygel
 b) the versions of gssdp and gupnp
 c) a wireshark trace of a successful communication between the device
and mediatomb and one between the device and rygel?

Preferably in a bug report, so that we can keep track of it.

As for streaming all audio: The PulseAudio support is somewhat
complicated. Sometimes it works, sometimes it doesn't. One part of this
problem is that you need to have the correct version of the PulseAudio
plugin, the other is that PulseAudio does the final HTTP streaming
itself, which then lacks the DLNA magic flags most of the devices rely
on.
