Sound Switcher Indicator is a sound input/output selector Ubuntu AppIndicator. It allows switching the current sound input and output (source and sink) as well as the specific output port with just two clicks.
Using it, can for instance switch between headphones, speakers and HDMI sound output with just two clicks. Or switch between several sound devices (sinks) without having to go to System Settings > Sound, etc.
The application needs PulseAudio to work and it gets a list of devices automatically thanks to the PulseAudio subscription capabilities.
The features provided by Sound Switcher Indicator are not something that's missing from Ubuntu, but this tool makes it a lot easier for those who constantly switch between speakers, headphones and HDMI sound for instance, and that should be very useful for some Ubuntu users.
