ScreenFlow: Captures the system sound without changing the current default output device and without publishing the virtual audio driver as a deviceДЄ quote from Jeff Moore, a CoreAudio Apple engineer, in reference to applications such as WireTap and Audio Hijack Pro:

WavTap: Adds a sound device to the list upon installation auto-selects the device when the WavTap application is started auto-deselects the device when the application is shutdown and reselects the previous deviceДЄudio Hijack Pro: Adds a sound device only when audio capture of the default system sound is selected removes the sound device when audio capture is no longer selected and reselects the previous device SoundFlower: Adds a sound device to the list upon installation kextДЄfter reading the author's comments, it appears the underlying goal is to be able to capture the system sound without publishing the virtual audio driver as a device (that would appear in the System Preference's list) and without changing the current default output device (or at least the appearance that the device has changed). Captures system audio using the SoundFlower. (Version 2.x uses varaudio.kext Version 3.x uses TelestreamAudio.kext) Captures system audio via an in-house developed. Captures system audio and application audio via an in-house developed. These features are branded as their 'Instant On' feature (InstantOn.kext). Captures an already-running application's audio with the help of the haxie 'Application Enhancer' (APE) from Unsanity Captures an application's audio by substituting a 'patch' framework for the normal amework when launching the application

Captures system audio via code based off of the open-source SoundFlower. kext that I believe does substantially what you want.ДЇor reference, here is how some popular commercial closed-source options work: This means that we always select a microphone when we connect it, in the end macOS can always select it.Take a look at the open-source WavTap, which is a simplified fork of the open-source SoundFlower virtual sound card driver. As in the previous case when recording a podcast, this is the most common task that is performed when a new microphone is connected to the system, although the system ends up remembering the input method when it detects it.

We can do this by clicking on the small arrow that we find next to the record button.ДЄs we see, this can be a most common action when working with audio files. One of the most common applications for audio recording on Mac is QuickTime and here we must always be careful to select the correct microphone. In this way, the system will mark the audio input equipment as default so that it is used both when making calls with FaceTime or in other applications. We can check if the microphone works correctly with the witness that we are in this window. If we want the microphone to pick up the greatest possible sound we should move the selector of the bar to the right.

By clicking on it at the bottom we will find a section called вЂinput volumeвЂ™ which is the microphone gain.

We will find a list of input devices, and simply click on the device we want to use.

At the top we find different sections and simply select вЂEntryвЂ™.

Go to System Preferences and look for the вЂSoundвЂ™ section.
