Hi Osmo:
I don't quite clear where do you want to use this functions call and
here are some informations I can give to:
1.You can get default sink and source in pulseaudio by functions:
> pa_sink* pa_namereg_get_default_sink(pa_core *c)
> pa_source* pa_namereg_get_default_source(pa_core *c)
These 2 functions will return you the pointer of default sink or
source,thus you can get name by sink.name or source.name.
You can also check this informations in pacmd:
$ pacmd
<<< list-sinks
<<< list-sources
the first one is the default device in generally.
2.In the Gstreamer said I don't know very well,seems that pulsesink and
pulsesrc have no default device,maybe you need to set them first and the
get these arguments as others by:
> g_object_get(G_OBJECT(pulsesink),"device-name",dev_name,NULL);
Hope this helps :-)

Gaining the trust of online customers is vital for the success of any company
that requires sensitive data to be transmitted over the Web. Learn how to
best implement a security strategy that keeps consumers' information secure
and instills the confidence they need to proceed with transactions.
