I use three opticals input (L, R, Dialog). It won't do anything special when two of them are active. The auto-switch (which is enabled by default and cannot be disabled in DOS2) only works in when one of the optical devices is started (when the optical becomes lighted), otherwise, it's ignored until you switch to it in the app.
