Yes, that is part of the standard mixdown of surround material into stereo. All the surround information is also mixed down as well. The only thing that is left out is the LFE channel, due to its reference level being 10 dB different than all of the other channels.
As previously noted, we will have a way to include this. However activating this feature will require reducing the output level by -10 dB, so don't forget to reduce your volume control when exiting this mode!
