Mute Intercom is a free Chrome extension that blocks annoying notification sounds from Intercom widgets.
Mute Me is a simple Touch Bar app to mute/unmute your microphone. When you’re in a meeting using Hangouts, Skype, Slack, or another voice application, it's good practice to stay on mute until someone speaks to you directly - especially if you’re meeting with three or more people. Mute Me helps you easily to do that.
Disconnecting your headphones or speakers from your Mac automatically selects the Internal Speakers. Any sound that was playing before is now shared with everyone around you. 🙀
Your Cyndi Lauper playlist? Yea, that's no longer a secret.
Relax monitors your audio output and takes action when it notices you switch back to your internal speakers.
