With Voice and Beep turned off, in-game audio still attenuated

It's impossible to turn voice com entirely off because even though beeps are turned off and voice receive volume is 0%, when someone uses in-game voice, the entire in-game audio is attenuated as if voice is enabled.

+1. I would like to have the option to turn that off out-right. I hate having the game audio lowered from someone else talking.
