I have two HDMI displays with speakers, a desktop audio system, a logitech HD Webcam with built-in mic, and a logitech USB headset. Switching from listening to music into doing a webex used to be a bit of a clickfest so I searched for a solution offering an easier way to manage so many audio input/outputs. Luckily I found AudioSwitcher right out of the gate as it worked perfectly for that use case. Better yet, I have several Apple TVs between my home and my office - AudioSwitcher also handles them without issue, allowing me to easily play Spotify into my home AV sound system whenever I want. Between this app and Shush, I have my audio setup fully dialed in. Props to people who develop genuinly useful apps that solve real problems so well.
