Possible Reasons Why Your Mic Was Not Recorded
1. You had the wrong mic selected
To fix this:
When recording from the Web App or Chrome Extension, change your microphone by clicking on settings and deploying the second drop-down menu to display all your available options.
For a more permanent fix, change your default microphone settings in your Chrome Preferences. You can also copy the following path and paste it into your Chrome's address bar and hit Enter: chrome://settings/content/microphone
2. You accidentally left your microphone "off" from your last video
To fix this:
When recording from the Chrome Extension, it's possible to toggle your microphone to "off." Make sure to turn it back on when you're ready to record with sound again!
