It should be made unequivocally clear in the specification that it is possible to capture audio output - not exclusively microphone input - even if the terminology used is "input" and "sink" - with an example of the canonical means to do so using the API's in the specification. 

The suggestion to use `getDisplayMedia()` to capture system sound outpu lacks a concrete minimum example. The expected result is not possible based on the tests that have tried.

Whether the term of art used is "sink" or "source", "input" or "output", when the code at https://github.com/w3c/mediacapture-main/issues/650#issue-534574931 is run at Firefox 70 and Nightly 73 the obbservable result is that only audio output is captured and recorded, not microphone. 

Is your position that capturing audio output using the above linked code is still considered to be capturing a "sink"?
