A Custom Linux: switchaudio.sh - switching pulseaudio output

A script if you use multiple audio output devices and Pulseaudio. For instance USB headphones and a regular internal sound card. This script makes it easy to switch between the different cards, and update any current applications to use the new output device.

To execute just copy to a bin directory like `/usr/local/bin` and run `switchaudio.sh --next`.

You can bind this script to a key shortcut in KDE : systemsettings -> Shortcuts and Gestures

You can also find it: http://pastebin.com/a6T3ezFs
