Muting sounds with SoundSource

The speaker icons shown next to volume sliders in SoundSource include sound waves that indicate the current volume level. In addition, those speakers also serve as handy dedicated Mute buttons.

This makes it possible to mute sound from both your Mac’s default output device, as well as alert sounds and sound effects, or from individual apps. Favorite apps and other apps that have played sound in the past 15 second span are shown automatically in the Applications list, with a volume control.

Clicking the Mute button for your Mac's Input device will prevent any audio from being heard from that device. SoundSource thus provides a very useful Mute button for microphones and other inputs.

Muting via menu bar

For quick access to muting, you can add any source or device to the menu bar. Select a source or device, open its detail view using the side button (chevron), then choose Show in menu bar from the Options menu. This places a meter icon in your Mac's menu bar—click it to quickly mute or unmute.

Muting via keyboard

For fast muting, use a global keyboard shortcut to display SoundSource, then use the arrow keys on your keyboard to select a device or application and mute it by pressing the Shift + Cmd + Down Arrow keys.
