David built a home theater PC and when he boots up, his sound card doesn't remember the settings to be able to watch TV. Leo says that's been a common problem and can be very frustrating. There has to be a way to save settings somewhere, but Windows isn't offering to do that. Leo has a hunch it's the source that should be saving it, and that would be the sound card driver. The chatroom says that the user access control (UAC) will prevent remembering.
PadreSJ says that there's a hack that if he uses an HDMI cable with Pin 19 removed, it'll not only remember settings, but HDCP will stop working as well.
