The biggest problem facing users who want to have surround sound in their home is the placement of the rear speakers. This is particularly challenging if 7.1 surround is what you are after. A new update fro Dolby 7.1 surround has been revealed.

The update adds a pair of new audio zones with a back surround left and back surround right placement. These pair with the two front zones to provide better 3D sound. The new setup feeds each of the new rear channels their own signal rather than using a single signal for both like the old system.

We aren't sure when the new system will land and if you will need a new receiver to take advantage of if you can somehow upgrade existing gear. I bet you need new gear.
