API Equivalent for "Leave Computer Audio"

Meeting SDK Type and Version
Meeting SDK, Windows, 6.1

Description
When I use the Meeting SDK, I’m not able to shut off the incoming audio from other panelists. The only way I can do it is by disabling ENABLE_CUSTOMIZED_UI_FLAG so the Zoom interface appears, and then I can go to the Microphone menu and choose “Leave Computer Audio”

I have searched the APIs and I cannot find an equivalent command.

How do I shut that audio off?

This is a significant problem, because it means the operator is stuck hearing their own voice echoing. I tried calling the api to set the speaker volume to 0, but that unfortunately shut down all sounds from applications on Windows, including our own!

I have found one work around, but it is a horrible hack. I can set the Zoom audio output to be a different device from the one our app is using.

Looking forward to some words of wisdom!

Thanks,
