Done.

Yes, that's exactly what's happening! I did all that, then I opened alsamixer
and the "Line" element was already muted by default, and unmuting it or
changing its volume didn't affect anything; I could still hear the audio coming
from both Headphones and Speakers no matter what.

Thanks for pointing the directions, I'll definitely open a ticket there, but
what title and description do you think I should choose? I'm not sure exactly
what this bug is and I wouldn't want to "guess" a title/description for it,
since I could be misleading...

Oh my God, thank you soooo much! It worked perfectly!!! Pavucontrol still shows
"Line Out" as "unplugged", but I can switch to it and it will still work as
expected. Thanks again!
