OK, set the input sensitivity of your analog input to 2.1V.
There is one other thing you should do, however, and that is to go into the Audio Processing Setup settings for the Oppo which control analog output except for Dynamic Range Control which also affects HDMI audio output.. The first item in that menu is Output Volume" which affects the level of the analog audio output. The default setting is Variable which allows the volume control on the Oppo remote to control volume. Instead set it to Fixed which disables volume control in the Oppo and sets the analog output level to maximum which ensures your maximum output level will be 2.1V. I suspect you may still notice a difference in level between the analog and digital outputs from the Oppo but setting the Output Volume setting to Fixed should minimise the difference.
