Re: [mediacapture-main] Support capturing audio output from sound card (#629)

Agree. 

Reading this language https://chromium-review.googlesource.com/c/chromium/src/+/1064373/

```
PulseAudio: Filter out unavailable inputs and refuse to open monitor inputs

If there are no available inputs, PulseAudio will, for some reason,
select the monitor of the current default sink as the default source.
...
this CL also explicitly returns
invalid AudioParameters for monitor devices, and explicitly fails to
open them as inputs - to be on the safe side.
```
it appears that Chromium just "refuse" to open certain devices - rather than fix the actual problem with PulseAudio being described, where Mozilla Firefox and Nightly do not have that problem, and using `pavucontrol` as a workaround confirms that selection of monitor devices is possible.

Perhaps you can actually fix whatever problem was reported at https://issuetracker.google.com/79580580 re PulseAudio in order  for Chromium to be in alignment with your evaluation?
