I'm interested also to know why.
Bumping this old thread precisely because of what Pineteam says. I'm curious as to why do we need to do the other actions (Intercom sw to INT, but volume at minimum...) to test the CVR even if the test is satisfactory just with the parking brakes on. I'm sure there's a reason for it but it's absolutely baffling why we need to do that if the test is OK anyway...
