Original commit message from CVS: 2005-08-22 Andy Wingo <wingo@pobox.com> * gst-libs/gst/audio/gstaudiosrc.h: * gst-libs/gst/audio/gstaudiosrc.c: Implement open_device and close_device in the ring buffer, like gstaudiosink. * ext/alsa/gstalsamixer.h: * ext/alsa/gstalsamixer.c: Not a GObject any more. Include a nifty macro to implement the interface without much code. Cleanups. * ext/alsa/gstalsasrc.h: * ext/alsa/gstalsasrc.c: Be a mixer. Open device and mixer in READY. * ext/alsa/Makefile.am: Add new files. * ext/alsa/gstalsamixerelement.c: * ext/alsa/gstalsamixerelement.c: Split element code out from mixer code so that alsasrc can be a mixer too.
