However we have to do this in a terminal, because there is a isatty check on the stdin, this is not friendly for automation/script to test audio pause/resume feature with aplay. Is it possible to remove the isatty check, so that we can do pause/result test with a single stdin redirection? Another possible fix is that we can make use of the SIGUSR2, so that we pause/resume stream by sending signal to the aplay process. @perexg Issue URL : https://github.com/alsa-project/alsa-utils/issues/155 Repository URL: https://github.com/alsa-project/alsa-utils
