After using Screenium, I can no longer hear any audio on my Mac. How can I bring back the audio?

Screenium relies on the audio routing software Soundflower to capture the system audio output. For this purpose the audio output is automatically set to Soundflower during the recording. When the recording is completed, the output automatically switches back to Built-in output. However, if Screenium is force quit or crashes during the recording, the audio output is not switched back to Built-in output. Therefore you might have to switch the audio back manually to bring back the audio.

Open the audio Midi Setup

Set back the sound output to Built-in Output
