Is the suggestion to file an issue at that specification?

Attempted to get audio using `getDisplayMedia()` using two different approaches, so far. Executing `getDisplayMedia()` once does not resolve to `MediaStream` containing an audio track. Executing `getDisplayMedia()` twice, once audio is being output, then navigating to the prompt again to select the same display device, where output is unknown, e.g., audio in the form of speech, initially results in at least half of the audio already having output before the second media stream containing no audio track is resolved by `getDisplayMedia()`.

What is the canonical procedure per any specification or implementation relevant to media streams and capture origin to capture only audio output?
