[pulseaudio-discuss] Sample format of default source

I'm trying to find a way in libpulse to query the sample format of the 
default source. Passing NULL to pa_context_get_source_info_by_name does 
not seem to work ("invalid argument").

The only way I can think of is to create a stream, connect it to the 
default source, call pa_stream_get_device_name (or index), and pass that 
name to pa_context_get_source_info_by_name. But that is a quite ugly 
solution. Any other way to get the default source's name?
