SND_PCM_TRIGGER_DONE(9)                      PCM API                      SND_PCM_TRIGGER_DONE(9)



NAME
       snd_pcm_trigger_done - Mark the master substream

SYNOPSIS
       void snd_pcm_trigger_done(struct snd_pcm_substream * substream,
                                 struct snd_pcm_substream * master);

ARGUMENTS
       substream
           the pcm substream instance

       master
           the linked master substream

DESCRIPTION
       When multiple substreams of the same card are linked and the hardware supports the
       single-shot operation, the driver calls this in the loop in snd_pcm_group_for_each_entry
       for marking the substream as “done”. Then most of trigger operations are performed only to
       the given master substream.

       The trigger_master mark is cleared at timestamp updates at the end of trigger operations.
