is there a distinction between "in-wall" vs "through wall" ?


BTW, I finally ran down the list of equipment requiring an equipment ground per the NEC and independent of manufacturer's requirements, it's in 250.114(3):

The following cord and plug connected equipment is required to be grounded unless protected by a system of double insulation:
A. Refrigerators, freezers, air-conditioners.
B. Clothes-washing, clothes drying, dishwashing machines; kitchen waste disposers; information technology equipment (your computer); sump pumps and electrical aquarium equipment
C. Hand-held motor-operated tools, stationary and fixed motor-operated tools, light industrial motor-operated tools
D. Motor-operated appliances of the following types: hedge clippers, lawn mowers, snow blowers, and wet scrubbers.
E. Portable handlamps.

So there is a requirement for computers, but not for home audio or video equipment unless it's stated in the manufacture's installation instructions.

Home Inspection: "A business with illogically high liability, slim profit margins and limited economies of scale. An incredibly diverse, multi-disciplined consulting service, delivered under difficult in-field circumstances, before a hostile audience in an impossibly short time frame, requiring the production of an extraordinarily detailed technical report, almost instantly, without benefit of research facilities or resources." - Alan Carson

Knock a hole in the wall, run your cord though, dangle some yellow caution tape around it and don't forget the orange cones.
