Original commit message from CVS: * ext/alsa/Makefile.am: * ext/alsa/gstalsamixer.c: (gst_alsa_mixer_interface_init), (gst_alsa_mixer_build_list), (gst_alsa_mixer_get_volume), (gst_alsa_mixer_set_volume), (gst_alsa_mixer_set_mute), (gst_alsa_mixer_set_record), (gst_alsa_mixer_set_option), (gst_alsa_mixer_get_option): * ext/alsa/gstalsamixer.h: * ext/alsa/gstalsamixeroptions.c: (gst_alsa_mixer_options_get_type), (gst_alsa_mixer_options_class_init), (gst_alsa_mixer_options_init), (gst_alsa_mixer_options_new): * ext/alsa/gstalsamixeroptions.h: * ext/alsa/gstalsamixertrack.c: (gst_alsa_mixer_track_new): * ext/alsa/gstalsamixertrack.h: Add enumerations (as GstMixerOptions). Make correct distinction between input/output tracks. Add capture/playback private flag. Use flag to decide on whether to set capture or playback volumes or switches. Use playback and record switches. * gst-libs/gst/mixer/Makefile.am: * gst-libs/gst/mixer/mixer-marshal.list: * gst-libs/gst/mixer/mixer.c: (gst_mixer_class_init), (gst_mixer_set_option), (gst_mixer_get_option), (gst_mixer_mute_toggled), (gst_mixer_record_toggled), (gst_mixer_volume_changed), (gst_mixer_option_changed): * gst-libs/gst/mixer/mixer.h: * gst-libs/gst/mixer/mixeroptions.c: (gst_mixer_options_get_type), (gst_mixer_options_class_init), (gst_mixer_options_init), (gst_mixer_options_dispose): * gst-libs/gst/mixer/mixeroptions.h: Add GstMixerOptions. * sys/oss/gstosselement.c: (gst_osselement_class_probe_devices): Rename Audio Mixer to OSS Mixer (similar to Alsa Mixer). Fix broken device detection on computers with multiple OSS sound cards.
