Your "memory palace" could simply be a row of doors where different sounds come from each one.

Or a jungle where you have to crawl and climb over obstacles to move around.

Imagination isn't just visual. Just because you can't "picture" something in your head doesn't mean you have no imagination.

That's really interesting! I'm probably just using my lack of visual imagination as a cop out. Do you have any examples of resources for constructing such a "memory palace"?
