Synchronized volume control for awesome wm
#!/bin/bash
# the script comes from this site: customlinux.blogspot.com/2013/02/pavolumesh-control-active-sink-volume.html
# This is an updated version that works with ubuntu 18.04 and sends notifications to awesome window manager via awesome-client. Remember - I'am not an original author of the script.
# finds the active sink for pulse audio and increments the volume. useful when you have multiple audio outputs and have a key bound to vol-up and down
