on the capabilities of audio capture refer to the documentation https://developer.apple.com/documentation/screencapturekit/ or watch the session "Meet ScreenCaptureKit".
Currently audio capture typically happens via virtual devices set up with 3rd party products. This requires additional installation and configuration by users.
Including the audio with the existing CMBuffers will make it easier to manage audio sync with video frames. Additionally, you can capture distinct audio tracks from multiple apps at once,
like a call with friends + screen content.
