OpenBSD NC4200: Simple script for audio output swapping for scrotwm.

Heyya,

I've written a simple script to alternate audio out between my laptop speakers and phone out. This script is intended for scrotwm, but also can be used on its own.

	# My scrotwm config
	# Programs
	program[swap_audio] = /usr/local/share/scrotwm/audioout.sh
	# Key Bindings
	bind[swap_audio] = MOD+Shift+a

	#!/bin/sh
	#
	# audioout.sh - Ahmad Zulkarnain 08/09/11
	# Script to alternate between audio master output and phone output.
	# Will be used by scrotwm. Copy to /usr/local/share/scrotwm/
	# and alter ~/.scrotwm.conf accordingly.
	# Variables for audio status
	master=$(mixerctl | grep master.mute | sed s/.*=//)
	phout=$(mixerctl | grep phone.mute | sed s/.*=//)
	# Program starts
	if [[ $master == 'on' ]];
	then
	mixerctl outputs.master.mute=off;
	mixerctl outputs.hp.mute=on;
	elif [[ $phout == 'on' ]];
	then
	mixerctl outputs.master.mute=on;
	mixerctl outputs.hp.mute=off;
	else
	mixerctl outputs.master.mute=off;
	mixerctl outputs.hp.mute=on;
	fi

As usual, feel free to copy this file and improve it. You can see by the Gist that there's 2 files, the first is .scrotwm.conf and the next one is audioout.sh (see the file name on bottom right of the embed).

The .scrotwm.conf is a snippet of configuration needed to make the script work with scrotwm's key binding. As you can see, I've set the key binding to Mod+Shift+a key. So whenever I press the key binding, the audio output will swap between speaker and phone out. Very simple. All I need to do is add the snippet to ~/.scrotwm.conf.

Then I need to save the 2nd file as audioout.sh and save it in /usr/local/share/scrotwm/. There's a few other default scrotwm's script inside there. Make sure the audioout.sh is executable, if not do chmod 755 or similar which is suitable for your environment. Then enjoy.

Previously I would need to manually mute/unmute both master and phone out as I sometime uses headphone. Now I can simply press Mod+Shift+a to swap between it.

Take note that this script can be used even without scrotwm. You just need to copy the 2nd file to your ~/ (home) and run it by typing ./audioout.sh or use another keybinding if available. Later.
