Yes, that seems to be the case.

Switching rather than using both simultaneously is more important to me, but
yes.

Yes, that would be ideal.

The first goal is what I am primarily interested in.

Running the above two commands results in no output at all. Either to my
headphones or to my speakers (sound stops after the first command, and the
second does not restore it).

This restores sound as it was before.

No. See above.
