This is a delay utility version $version. The snd-aloop ALSA driver is
used to send all PCM streams back to the user space and the alsaloop
utility is used to send this stream to a real hardware.

<output_card> is ALSA card index (number) or string card identifier
<device> is ALSA device number

Use 'aplay -l' to list available cards and devices.

Operation modes:
  -h, --help		print this help, then exit
  -q, --quiet		quiet mode
  -y, --yes		do not ask any questions - answer is always yes
  -c, --clean           clean temporary directory
  -r, --revert          revert configuration changes (modprobe, pulse-audio)
  --tmpdir=<DIR>        set temporary directory
Alsaloop options:
  --pdevice=<DEV>       force playback device
  --cdevice=<DEV>       force capture device
  --pctl=<DEV>          force playback ctl device
  --cctl=<DEV>          force capture ctl device
  --one=<ARG>           pass this argument to last thread
  --arg=<ARG>           pass this argument to all threads
  --mix=<ARG>           redirect ALSA mixer controls to OSS mixer
			(default is Master)
  --pa			Redirect pulse-audio to alsaloop

Note: For devices, the string %s is replaced with the card index
      and second string %s is replaced with the device index
      and third string %s is replaced the substream index (0-7).
      Example: hw:%s,%s,%s    (card, device, substream)
