You can now record the audio from SoundFlower in OBS.Use the menu shown here to pick your iOS device for display or recording. Open 'System Preferences -> Sound' and set the output to the device just created.

Open Audio MIDI Setup, on the lower right corner, click '+ -> Create Multi-Output Device', add both SoundFlower and Main Speaker.This will output the audio from device to main speaker. Go to 'File -> New Audio Recording', and select the device in the drop down menu next to record button (but don't hit record). First connect the device via cable and open QuickTime.However, the setup is quite complicated and not very flexible (included below).Īppendix (how to use SoundFlower to workaround this) The workaround I found is to record the main speaker output (using SoundFlower or other similar tools) since QuickTime will output the audio from iOS device to main speaker of my MacBook. This seems like QuickTime use a different mechanism to grab the audio input from iOS device, and I am not aware of any other applications can do this. But how does QuickTime works? The audio input option from iOS device is in the QuickTime even when the device is not enabled in Audio MIDI Setup (and when enabled, the device is listed twice with slightly different names). The frustrating thing is that I cannot record both in OBS, it seems like iOS device can only operate in 1 of the 2 modes that provides either video (screen cast) or audio via USB, but not both. When I close the OBS (or remove the video input from the iOS device), however, the audio input in the MIDI setup works, and I can record audio in OBS via 'audio input capture'. However, with OBS opened, the audio device immediately became disabled about a second after I click 'Enable' in the Audio MIDI Setup. After a bit research, I found audio input can be enabled using 'Audio MIDI Setup'. The video is available in 'video capture device', but the audio cannot be found anywhere. I then tried OBS as QuickTime is not very flexible. I then opened QuickTime Player, click 'File -> New Movie Recording', and select the iOS device as video and audio input from the drop down menu next to the record button, and everything works fine. I want to record both screen and audio from iOS device using my MacBook, so I connected the device to my computer using cable.
