 If you're trying to play music and sound effects into Zoom using something like the Rocaster Pro 2 and the Ecamm Live Virtual Mic, and you're finding that your guests can't actually hear it, it's likely down to your Zoom audio settings. You see, they have something in there called background noise suppression, and basically Zoom is thinking that all of that other stuff is background noise that needs to be removed. We can fix this by going into your Zoom settings. You'll see that Zoom optimized audio auto is the default. Changing this to low should allow that music to come through. However, I would recommend if you've got a good audio setup, use original sound for musicians down here. If you are using speakers to hear the audio back from the meeting, then allow echo cancellation, otherwise leave it off. One thing to note is, although you've enabled it here, you will also need to actually toggle it on each and every time you start a meeting. You can find that button in the top left of the Zoom meeting screen.
