@guidou Kindly run the code at https://github.com/w3c/mediacapture-main/issues/650#issue-534574931 at Firefox, Nightly and Chromium. 

Select `"Monitor of <device>` at the prompt. Observe the different output. Firefox captures _only_ audio output, the desired result. Chromium does not expose `"Monitor of <device>"` thus microphone is captured, not the audio output from `speech-dispatcher` calling `espeak-ng` via `spd-say`. 

Is there any compelling reason to not expose `"Monitor of <device>"` at Chromium?

What solution do you suggest to achieve the requirement of the use case if neither `getUserMedia()` nor `getDisplayMedia()` are intended to accomplish the task at Chromium?
