Sound Switcher Indicator shows an icon in the indicator area or the
system tray (whatever is available in your desktop environment).
The icon's menu allows you to switch the current sound input and
output with a single click.
The appearance of the menu can be customised. For example, devices
and ports can be given custom display names, hidden etc.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
