Sound transmission on optics and HDMI

Simultaneous transfer of a digital sound is VERY necessary
both on an optical cable and on the HDMI cable AT THE SAME TIME! Now it is possible only in the STEREO mode. It is necessary in order that each time not to get into settings and not to recustomize the channel of a conclusion of a digital sound. I have two different sound receivers. To one HDMI, is connected to another an optical cable.
