If you've changed the setting so that audio records automatically, this only applies to the following meeting tools: Zoom, Google Meet, and Slack Huddle meetings.
For Slack Huddles:
1. You'll need to click on 'Open mini window' in order for the the audio to start auto-recording.
2. Make sure your meeting setting is set to record automatically or "Ask me if I want to record".
Note: Unfortunately the 'video' / Screen Capture cannot get captured in Slack Huddle (due to recent changes in Slack).
