How to troubleshoot microphone issues (e.g. Zero Volume)

Here's how to troubleshoot Zero Volume issues:

1. Turn up the Microphone Input Volume

Windows: Sound > Recording > Properties > Levels. Slide the microphone slider all the way to the right.

Mac: System Preferences > Sound > Input. Make sure the appropriate microphone is selected. Slide Input volume to the right. When you talk, the Input level indicator should indicate that it's picking up sound.

Windows 7 or Windows 8
Windows Vista
Windows XP

Mac microphone settings:

2. Quit Chrome

If the above does not work and you're using the Chrome browser, then completely quit Chrome, re-open and retry.
