If you are experiencing issues with audio on Mac OS X or macOS, it's a good idea to Delete your Audio Preferences, as it's possible that they may have become corrupt.

Issues such as glitches, disconnects, dropouts, and generally odd behaviour can often be resolved in this way.

You need to ensure you empty your trash and restart your Mac after deleting these files.

Make sure to Restart your computer after you empty the Trash. When you do, the Preferences will regenerate themselves with their Default Values.
