Provides omxanalogaudiosink and omxhdmiaudiosink elements on the Raspberry PI. - omxanalogaudiosink is capable to render raw mono or stereo audio through the jack output. - omxhdmiaudiosink is capable to render raw audio up to 8 channels and transmit ac3/dts(IEC 61937) through the HDMI output. - sinks provide a clock derived from rendered samples - sinks support the GstStreamVolume interface by implementing the volume and mute properties. https://bugzilla.gnome.org/show_bug.cgi?id=728962
