alsa-project/alsa-utils pull request #81 was opened from aditpape: Terminating stream with CTRL-C will set in_aborting flag which is used to leave any write/read loop on the ALSA device. After ending the read/write loop aplay tries to drain the stream which is not required and can also lead to malfunctions: -If user interrupts a blocked/non responsive PCM (e.g. usb uac2 gadget which does not consume data due to stream stopped by host) it will successfully terminate the write loop but will hang again in drain call. This would require to hit CTRL-C again to unblock which should be avoided. Aplay currently anyhow allows signal handler to get invoked only once.
