How do I turn on audio?

Keysight does not produce any sound.

This is intentional; Keysight would not be able to deliver high quality and low latency audio sufficient for live performance or recording. As such, rather than deliver a poor experience, Keysight deliberately does not produce sound to force users to use fit-for-purpose tools to create their own sound.

To find out more about using Keysight and a Digital-Audio-Workstation (DAW) application simultaneously to create beautiful sound and visuals, see this guide.(*)

Using audio files in a render

The only capacity in which Keysight uses sound is as an option during render-to-video(*) operations. An external audio file can be added to the video file during rendering as a means to bypass doing this in a video editor later and needing to re-encode the video.
