This is a workflow for Alfred.

This workflow supports quickly switching sound input and output devices.

It offers hotkeys to quickly switch between three input favorites and output favorites. Those can also be triggered using Alfred Remote.

Once installed, use the fetchaudiodevices command in Alfred. Once you have selected either "Outputs" or "Inputs", the workflow will copy a list of devices to the Clipboard. This is a convenience feature to support filling the Ignorelist, Output Favorites and Input Favorites. (See below)
