The noise from the speakers is a part of the auto re entry software down load.
Pretty sure the capsule is safe for re entry but probably not so sure that I’d like to ride it down
What got my attention about the noise (that sounded like it was from The Hunt for Red October) is that the very seasoned astronauts did not know what it was and had to call in for information.
That is a strong indicator of poor training or communications or a new problem—none of those good.
