[ Please keep me in CC as I'm not subscribed to the list] Hi All, Hello all, I’m using aplay and arecord utilities for playback and capture. I need to capture the timestamps for the first and last audio samples that arrive at the driver level. For this I’m capturing the CLOCK_MONOTONIC_RAW timestamp at the .trigger(for playback & capture) callback in SNDRV_PCM_TRIGGER_START case – is it the correct timestamp for the first audio sample arrived at the driver level? Similarly does .trigger callbacks SNDRV_PCM_TRIGGER_STOP gives the last audio sample timestamp? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
