Well, each app has its mode of operation. Configure in your alsa
configuration files the global default, then create / configure your
esound (esd) preferences, and finally configure your GStreamer
preferences.

The stack is as follow:

I can't tell whether you run Esound or not, if you do run it, there's
no point in telling Rhythmbox to output to a different "device" or
"daemon", since esound can be instanced only once.
In the contrary, if GStreamer is bound to ALSA directly, you might
select the proper device via GStreamer options. At least the
"alsasink" element knows how to select different ALSA devices.
Have a look at the README.Debian, and try to run the pipeline therein
with an ALSA device, something like:
gst-launch-0.8 gnomevfssrc location=/path/to/my/musicfile.ogg ! \
spider ! volume ! audioscale ! audioconvert ! \
alsasink device="default"
Where "default" is your ALSA device.
I think there's no point in supporting such configuration items via
command-line options for any GStreamer program, but your particular
request makes sense. GStreamer provides support of command-line
parsing of GStreamer related command line arguments, but you can't pass
things such as "the device parameter of the alsasink element", you have
to rework your GST pipeline.
A quick hack for you would be to recompile Rhythmbox to suit your
needs (ie. with a hardcoded ALSA output device).
