Sound is made out of matter. The electric field force is an emergent
property of the interactions between electric charge and photons. I think if
you're going to disagree that sound is made out of matter, then it's a
question of semantics you're asking, unrelated to the universe at large.

"Force" is an emergent measurement. It's not an actual thing. It's a
statistic. Just like the acceleration you feel sitting in your chair isn't
a thing, it's an effect caused by the earth and your butt taking convergent
paths through space-time.

Electrons repel each other because their statistical interaction with
photons they create is such that they're more likely to wind up farther away
from each other than closer to each other. The "force" is the fact that we
can measure this.

There's also "information" like "what color is this quark" or "how much
charge does this object hold" that don't disappear. That's why black holes
rotate: angular momentum is a form of information that doesn't disappear.
