Cambridge FPS2000 Digital speakers - mix digital + analog?

I've got a set of Cambridge FPS 2000 4.1 speakers. These speakers have both
digital input and analog input. Unfortunately, when the digital input is
connected, the analog is muted.

My wifes Microsoft DSS USB speakers can use both the USB and analog inputs
at the same time.

Is it possible to hack thE FSP 2000's so I can use both the analog and
digital inputs at the same time?

What I'm hoping to do is connect my main PC digitally and then another PC to
the front analog inputs.

Thx!

I doubt you'll find anyone who has reverse engineered it to
do this, so you are the pioneer and left with DIY starting
out with nothing... If you can provide enough of a
description of the circuit used and the relevant chips and
switching mechanism (might be logical, not mechanical
switching) that might be a start... but no expectation of a
successful outcome either.
