In this case, we might be again in capture state UI out of sync with the device mute state.
It seems to me that, in the usual case of capturing with only one device, UA should instead deny the request.

It is really only when there are multiple capture devices that is fine to do what you are suggesting (In that case the capture state UI will also be in sync since at least one device will restart capture).

It seems a note for implementors stating the reasons to override and/or deny might be helpful.

The reference '[=pausing all input sources | pausing policy=]' appears to have inconsistent linking syntax. Consider using consistent reference formatting throughout the specification.

Suggested change
