Audio cables are an analog signal, this means signal integrity matters more as it has a direct impact on sound quality. We use gold conctact on things because it prevents corrosion and has lower resistance. On a HDMI cable it won’t impact quality at all (it’s digital) but might reduce corrosion enough to increase the life of the cable.
Nope. There is no data to back that up.
