A DI-box with ground lift does not interrupt safety ground.
It just ensures that there is no ground connection via the
audio path. Both items connected to it will (should) still
have their own safety ground.
Whether it will reduce interference from MIDI in a sound
card is questionable. MIDI is isolated anyway. If anything
of it leaks into the analog audio path that means the sound
card has a problem.

A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris

All computers
do that. Just put a DI-box with ground lift between your
audio interface and the speakers and the noise is gone.

And get someone electrocuted. That doesn't happen on my watch because
they'll never get it plugged in, I would not allow it. There are several
ways to fix a noise inducing ground loop, but a ground lift adapter is not
one of them.
