I just got a KDL-55W802A and I'm trying to decide the best way to hook up a receiver and 5.1 speakers.
1) Connect all devices (DirecTV, BD, XBox, AppleTV) via HDMI to a Sony receiver such as Sony STR-DN1040, so that Bravia Sync will work to control volume, etc. Output HDMI from the receiver to the TV. Set the TV "Speakers" to "Audio System" so that the TV speakers are disabled (not sure if that is the right way to disable TV speakers). Would the TV remote then control the receiver via Bravia Sync? The disadvantage I see with this is that there is only one HDMI cable going to the TV for all devices, so I don't know if there would be any way to automatically have different TV picture settings for the different devices. You wouldn't want the same TV settings for Blu-Ray and XBox.
2) Connect all devices (DirecTV, BD, XBox, AppleTV) via HDMI to the TV. Output digital audio to the receiver (no need for a Sony receiver, I'd just use my old Panasonic receiver) using the optical audio out of the TV. Set the TV "Speakers" to "Audio System". Set the TV "Audio Out" to "Variable" to adjust the volume with the TV’s remote control when using an external audio system. With this setup, I would be able to have different TV picture settings for each device, but I'm not sure if the TV's optical audio output will pass through all of the audio, or if "Audio Out"-"Variable" works well through the optical output.
Neither of these seems ideal, but I'm wondering if both of them will work.
I'm also wondering if perhaps there is a better way that I don't know about when hooking up all the devices to a Sony receiver. For example, if Bravia Sync was smart enough to be able to change the TV's settings based on the device selected by the receiver. Say I selected the XBox input on the receiver, and I could configure the TV to have different picture settings for this receiver input. I don't know if Bravia Sync has gotten that advanced. I'm thinking probably not, and that a single HDMI input to the TV can have at most one set of TV picture settings associated with it. Of course I could manually change the TV settings when I want to play XBox, setting "Preferences"-"Scene Select" to "Game", etc., but that seems like a major pain.
Please give me some feedback if you can, and tell me how you have your audio system hooked up.
