Third-person high heel footstep sounds are missing

[redrootcat]

In third-person view, I don't get any high-heel footstep sounds when walking. However, in first-person view, the sounds work, and they also work when walking with a weapon drawn.

Usually it's the first-person sound effects that go missing, but my issue is a bit different.

I suspect that Immersive Sounds - Compendium is conflicting with Heel Sound, but I don't see any related file overwrites.
