Should the alsasink actually pause the ALSA device upon a pausing the pipeline? The benefit would be if the ALSA-device have configured long buffers/latency, the audio would be paused instantly instead of playing until buffer is empty. <br></div><div dir="ltr"><br></div><div dir="ltr">Looking into the code of gstalsasink, there does not seem to exist any callbacks from gstaudiosink notifying on pause and gstalsasink has not registered for change_state callbacks.
