- * pa_stream_new(). At this point the audio sample format and mapping of

+ * pa_stream_new() or pa_stream_new_extended(). pa_stream_new() is for PCM
+ * streams only, while pa_stream_new_extended() can be used for both PCM and
+ * compressed audio streams. At this point the application must specify what
+ * stream format(s) it supports. See \ref sample and \ref channelmap for more
+ * information on the stream format parameters. FIXME: Those references only
+ * talk about PCM parameters, we should also have an overview page for how the
+ * pa_format_info based stream format configuration works. Bug filed:
