Surely? Images play at <120Hz and sound requires you to run at or above the nyquist limit which for human hearing has the standard of 48kHz.
So all AV systems run image and sound separately and thus you can affect them separately.
(I assumed you assumed the changing colors displayed on the pixels with 120Hz somehow drive the sound which needs to change at 48000Hz)
Anything but separate inputs makes no sense giving the magnitudes different frequencies at which it needs to be driven. Also, the color/brightness of a pixel does mean nothing for the sound.

I mean, can you play video without hearing e.g. a 120Hz hum?
Hopefully? I guess this depends on the decoupling. Or they just highpass it and leave that region to the sub.
