/*
 * Due to the PCM pipe implementation of snapcast input we cannot know track start/end
 * it's all a long stream (although we detect idle situations)
 *
 * So, we cannot push metadata on start of track as we don't know when that is.
 *
 * I.E. we push metadata as we get an update, as we don't know when an update
 * is complete (different meta supported in different stream interfaces)
 * it is the streamreaders responsibility to update metadata and
 * trigger a client notification.
 *
 * I.E. we need to suppply the client notification mechanism.
