Original commit message from CVS: Patch by: Brian Cameron <brian dot cameron at sun dot com> * sys/sunaudio/Makefile.am: * sys/sunaudio/gstsunaudio.c: (plugin_init): * sys/sunaudio/gstsunaudiomixerctrl.c: (gst_sunaudiomixer_ctrl_build_list), (gst_sunaudiomixer_ctrl_new), (gst_sunaudiomixer_ctrl_list_tracks), (gst_sunaudiomixer_ctrl_get_volume), (gst_sunaudiomixer_ctrl_set_volume), (gst_sunaudiomixer_ctrl_set_mute), (gst_sunaudiomixer_ctrl_set_record): * sys/sunaudio/gstsunaudiomixerctrl.h: * sys/sunaudio/gstsunaudiomixertrack.c: (gst_sunaudiomixer_track_init), (gst_sunaudiomixer_track_new): * sys/sunaudio/gstsunaudiomixertrack.h: * sys/sunaudio/gstsunaudiosrc.c: (gst_sunaudiosrc_dispose), (gst_sunaudiosrc_base_init), (gst_sunaudiosrc_class_init), (gst_sunaudiosrc_init), (gst_sunaudiosrc_set_property), (gst_sunaudiosrc_get_property), (gst_sunaudiosrc_getcaps), (gst_sunaudiosrc_open), (gst_sunaudiosrc_close), (gst_sunaudiosrc_prepare), (gst_sunaudiosrc_unprepare), (gst_sunaudiosrc_read), (gst_sunaudiosrc_delay), (gst_sunaudiosrc_reset): * sys/sunaudio/gstsunaudiosrc.h: Add a SunAudio source plugin. Support stereo and right/left channel gain in the mixer plugin. Support the RECORD flag so that you can switch between line-input and microphone in gnome-volume-control. Code cleanups like using an enumerator for track number instead of an integer. Fixes #344923.
