Hi, 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? Regards, Magnus
