# Use PIR to switch connection between left channels of output and input (tips of 3.5mm jacks)
# Connect grounds of these two together (maybe you will not need it - depending on your soundcard)
# Power up PIR
# Launch this script
# Use alsamixer and some GUI recorder (like audacity) to tune volume to some usable level

# Wake up
