All pins are wired straight through. Tried breaking the shield at one end to no effect. The outer cable shield was tied to the connector shell at either end, but not tied to any of the grounded pins (5-8 or 10).
Network cables not shielded, but computer frame is also grounded via a couple USB cables (to UPS and printer).
Hum bars present with only VGA connected. Audio buzz present with only audio cable connected. Connecting both gives bars and buzz.
