Original commit message from CVS: * ext/alsa/Makefile.am: * ext/alsa/gstalsadeviceprobe.c: * ext/alsa/gstalsadeviceprobe.h: Helper functions to add device probing via the GstPropertyProbe interface to a class. * ext/alsa/gstalsamixer.h: Comment out GST_ALSA_MIXER, it returns a struct that's not used. * ext/alsa/gstalsamixer.c: (gst_alsa_mixer_open): Add some debug info. * ext/alsa/gstalsamixerelement.c: (gst_alsa_mixer_element_interface_supported), (gst_implements_interface_init), (gst_alsa_mixer_element_init_interfaces), (gst_alsa_mixer_element_class_init), (gst_alsa_mixer_element_finalize), (gst_alsa_mixer_element_init), (gst_alsa_mixer_element_set_property), (gst_alsa_mixer_element_get_property), (gst_alsa_mixer_element_change_state): * ext/alsa/gstalsamixerelement.h: Add 'device' and 'device-name' properties. Add GstPropertyProbe for device handling (gnome-volume-control will need that).
