The audio is quiet , even if you overload the video with too much contrast no hint of a buzz .

I'm getting a 404 file not found when trying to download the schematic, but the volume control is likely a few hundred kohms or more, so using 10k resistors on the input will only reduce the signal by 5% or less. Tying the L and R to the volume control with 10k resistors prevents the L and R DVD outputs from overloading each other.

If you have disconnected the TV volume control / audio amp circuit from the detector, varying the video level should have no effect.
