This app simply switches the Audio in/out as can be easily done from the System->Preferences->Sound panel. It does not lock the selected devices at all. If for instance I run "Zoom", it will automatically switch to the audio devices it remembers from its previous run.

This apps works! Just what I was looking for. I connect my MacBook Air with an old iMac as an external monitor. The audio kept switching back and forth during my Zoom calls or music. This app locked in my audio. After a lot of troubleshooting, nothing else worked. Thank you developer!

I recently got a 2019 MacBook Pro and a USB-C dock that has a headphone jack. I hoped this app would help keep the audio output running through the dock's headphone jack when I am plugged in, but it doesn't. I can select the right output when attached but when I disconnect and reconnect again it doesn't select anything.

I have an issue using WebEx for meetings. Some how my sound output switches to DisplayPort, which are speakers builit-in my monitor. There are no controls available and I cannot disable it.
