Switch Audio Devices on Your Ubuntu With The Snappy Indicator Sound Switcher
Indicator Sound Switcher is a sound input/output selector for the Ubuntu desktop. To use it just click the Sound indicator, select Preferences, and then configure your audio set-up in System Settings. Hit ‘Ok’and you’ll be good to go.
This simple indicator app will also be handy if you are one to have multiple audio sources on your desktop as it will be able to speed up the process of switching from your laptop’s built-in speakers to headphones and from a USB headset to the built-in microphone, etc.
Dmitry Kann, the applet’s developer, writes on the project’s GitHub page that “It shows an icon in the indicator area in Ubuntu’s Panel. The icon’s menu allows you to switch the current sound input and output (i.e., source ports and sink ports in PulseAudio’s terms, respectively) with just two clicks”.
The latest version of Indicator Sound Switcher applet is rewritten in Python 3 and supports graphics card profiles and it requires PulseAudio 4.0 to run.
Installing Indicator Sound Switcher on Ubuntu 16.04 LTS
You can either download and manually compile the applet from source by cloning or by grabbing the source code from GitHub or you can add the indicator’s official PPA to Ubuntu Software Sources and install it on your desktop via the commands below in a new Terminal window:

If you don’t want to add another PPA you can just download a pre-built installer instead.
