GstAudioClock makes it easy for elements to implement a GstClock, they simply need to provide a function that returns the current clock time.
This object is internally used to implement the clock in GstBaseAudioSink.

GstClockTime (*GstAudioClockGetTimeFunc) (GstClock *clock, gpointer user_data);
This function will be called whenever the current clock time needs to be calculated. If this function returns GST_CLOCK_TIME_NONE, the last reported time will be returned by the clock.

GstClock* gst_audio_clock_new (const gchar *name, GstAudioClockGetTimeFunc func, gpointer user_data);
Create a new GstAudioClock instance. Whenever the clock time should be
calculated it will call func with user_data. When func returns
GST_CLOCK_TIME_NONE, the clock will return the last reported time.
