Or is it by design that walking/jogging doesn't make any noise (from the footsteps) at all?

There's also this collision mesh issue in the "bone room" (flat no 1.6):

Would be great if Chasing Static could be released here on GOG as well, by the way.

The sound issues seem to have been sourted out with the patch, thanks for the quick fix.

Came across another collision mesh that's a bit too generously dimensioned (in Hannes Winkler's flat, where you can pick up the guitar):
