Getting your Mac to stream audio can be a bit tricky process. Kast seems to acknowledge this issue on their support guide as well.

As a workaround, Kast recommends using the web version of the app. Visit the Kast Web App and login with your credentials. Start a watch party and see if that resolves the Kast audio not working on Mac issue.

The web version has exclusive tab audio for Chrome tabs in addition to the standard audio options on Windows and Mac computers.

This allows you to share the audio from Mac more easily than from the desktop app. However, do note that when using Kast Web on your Mac, you will not be able to stream audio when sharing a browser tab.

The Kast audio not working issue can occur on your Windows and Mac system.

Check your audio input and output settings to see if that helps. If not, you can use third-party audio software like VoiceMeter to fix the problem.
