The good news if that in the audio area surround sound formats will not change (for the time being) with the introduction of 3D into a home theater setup. However, depending on what home theater receiver you have determines how you might make the physical audio connections between a 3D-enabled Blu-ray Disc player and the home theater receiver.
In other words, if you really want to be fully 3D signal compliant across the entire connection chain of your home theater system, you need to have a receiver that is 3D compliant by having HDMI 1.4a connections, especially if you rely on your home theater receiver for video switching or processing.
However, you can avoid this additional costly upgrade by planning ahead. Find out three ways you can still use a non-3D compliant home theater receiver with a 3D TV and 3D Blu-ray Disc player.
