Recadio is the best way to avoid the very annoying auto-switch when connecting a new audio device.

For a given combination of audio devices, it remembers your preferred input/output. If you want to change your preference, just use the menubar dropdown to select a new one and it will be remembered.

How to use it

If you're the visual learner, skip this text and go to the video below.

Recadio is a menu bar application. Once you open it, you'll see a new icon on your menu bar that looks half headphones, half alien.

Pro tip: command click + drag menu bar items to your favorite location.

Clicking on the icon will open the audio devices list, showing the currently selected input and output devices.

When you select an input/output from Recadio, it'll remember it as your preferred input/output for the current combination of devices. If you don't select anything, it'll behave with the default macOS device switching.

This means you have to select the device at least once within Recadio for the app to remember your choice.

FAQ

I'll keep this section alive with new QAs as I receive them

Q: I got an alert saying "Recadio can't be opened because Apple cannot check it with malicious software." and I can't install it.

A: That happens because I'm not subscribed to the $99/year Apple Developer program, so they try to scare people with that message. They have a website explaining how to install the app if that happens.

The summary is that you have to go to Settings / Privacy & Security, scroll down up to the "Security" section, and click on "Open Anyway".

Many people have requested that I subscribe, and I might consider it at some point, but it doesn't make financial sense for now.

Q: I selected a device in the macOS system preferences but Recadio doesn't remember my choices.

A: If you selected the device in the system preferences menu, there's no way for Recadio to know if it was you or the system making the selection. Therefore that selection is ignored. Only selections within Recadio will be remembered.

Q: Why does this app have a minimum macOS version requirement?

A: It requires significantly more work to make the app compatible with older versions of macOS. If there's enough interest I'll work on a release that is compatible with versions older than Ventura (13.0.0)
