Когда приложение AudioRecorder приостановлено, источник gstreamer alsa по-прежнему открыт PCM.
Я пытался вызвать unprepare, закрыть, когда состояние PLAYING_TO_PAUSED.
gst_alsasrc_change_state ()
.,.
case GST_STATE_CHANGE_PLAYING_TO_PAUSED:
gst_alsasrc_unprepare(alsa);
gst_alsasrc_close(alsa);
.,.
, но gstreamer по-прежнему вызывает snd_pcm_readi (), как показано ниже

Как освободить PCM в gstalsasrc.c, когда он остановился?
Вот журнал
